Overview of Upfront CFD

CFdesign is built upon the Upfront CFD Solution Platform. The platform is shown:

There are six fundamental pillars of Upfront CFD, each shown as a separate item in
the graphic. Each pillar represents a part in the process of performing a CFD analy-
sis. The most significant aspect of this concept is that the process is repeatable--
multiple design iterations can be analyzed, compared, and communicated with
those in the design chain efficiently and effectively. Each pillar is described in more
detail below:

CAD Integration

Starting in the CAD system of your choice, the component or assembly model you
build is all CFdesign needs to deliver a reliable fluid flow and heat transfer simula-
tion. A direct link to the major geometry engines eliminates the need for IGES,
STEP, or STL. Make a change to the model in your CAD system, and the change will
be a part of the CFdesign analysis.

Mesh Generation

CFdesign employs finite element mesh generation with numerous intelligent algo-
rithms to make the process automatic and transparent. By using automatic,

Getting Started
unstructured meshing, CFdesign quickly meshes complicated (real world) geometry
without forcing the user to become an expert in the application of mesh generation
tools. Assignment of the mesh distribution to geometry is virtually automatic, and
is based on a highly detailed geometric interrogation of the geometry.

Tools such as Shell surfaces allow significant reduction in overall mesh sizes by
allowing the inclusion of solid surfaces within three dimensional volumes. Mesh
Enhancement automatically refines the mesh to focus nodes and elements in areas
of high physical gradients. Finally, new technology has been developed to mesh
large assemblies more efficiently, using less computational resources.

Simulation Scope

CFdesign solves the mathematical equations which represent heat and momentum
transfer in a moving fluid. The finite element method is used to discretize the flow
domain, thereby transforming the governing partial differential equations into a set
of algebraic equations whose solution represent an approximation to the exact (and
most often unattainable) analytical solution. The numerical formulation is derived
from the SIMPLER solution scheme introduced by Patanker1. More detail is available
in the Technical Reference.

The influence of Fluid-Structure Interaction is a very significant element in many


mechanical devices. The CFdesign Motion Module brings this capability to the world
of product design as a key element of Upfront CFD. Through simulation, this Module
allows understanding the interaction between fluids and moving solids to be inte-
gral to the product design process.

The flow analysis is often just the beginning in many analysis-design projects.
Results from CFdesign can be applied as structural boundary conditions for subse-
quent analysis with many popular FEA packages. Aerodynamic and hydrodynamic-
induced pressures as well as temperatures can be interpolated directly onto the FEA

mesh. This very powerful capability completes the analysis circle, and is a major
integrating factor of CFdesign into the Design Supply Chain.

Simulation Speed

The intuitive user interface in CFdesign makes setting up the simulation very easy.
Using engineering language, the user simply applies the material and operating
conditions that are needed. Combined with many intelligent algorithms, analysis
set-up is fast and easy for users with no CFD experience.

In many design situations, running many what if scenarios is the key to the opti-
mal design. Because of time constraints, a single license often just wont get the
job done. With the Fast Track Option, our on-demand licensing plan, engineering
groups can temporarily ramp up their analysis capability in order to get the job
done quickly. Unlike an ASP or main frame scheme, this system allows engineer-
ing groups to utilize in-house computer resources without having to send out pro-
prietary data over the internet.

Design Review

Results are displayed at every step of the calculation. The user can interact with the
model, and view results real-time using cutting planes, iso surfaces, xy plots, and
particle traces.

Because CFdesign is a design tool, it is very important that results from multiple
analyses be viewed, compared, and contrasted easily. The Design Review Center
makes it easy to get a true apples-to-apples comparison between all of the analy-
ses in your project.

Project Collaboration

Sharing results with other members of the design supply chain is easy using the
Dynamic Image, a part of the Design Communication Center. Using our free plug
in, interactive images can be viewed in PowerPoint, Word, and Internet Explorer.
The person viewing a Dynamic Image can pan, zoom, and rotate the model, to see
your results from every angle.

Getting Started

Starting CFdesign

Direct launchers for Pro/Engineer, Inventor, Solid Edge, and Solid Works are

included in the CFdesign installation. Additionally, a new analysis can be created
from a Parasolid or Acis file by launching CFdesign from the Desktop or Start Menu.
The details of how to use each launcher are discussed in the following table:

Parasolid Start CFdesign from the Desktop using the CFde-


(.x_t) or Acis sign shortcut icon:

New Analysis

A new analysis is always created from geometry.

CFdesign Users Guide


Getting Started

When CFdesign is launched from a CAD system, the following dialog will prompt for
an analysis name:

The analysis name can (and often should) be different from the CAD part or assem-
bly name. The reason is to allow multiple analyses based on the same CAD model
to co-exist in the same directory and not overwrite each other, even though the
geometry has changed from one analysis to the next.

When CFdesign is launched from the Desktop to create a new analysis from
an existing Parasolid or Acis file, hit the New icon in the CFdesign Toolbar:

and the following dialog will come up:

Make sure the Analysis bullet is selected. Select the desired geometry file (its name
will appear in the File Name field after it is picked), and enter an analysis name in
the Analysis Name field. Hit OK.

CFdesign Users Guide


Getting Started

Existing Analysis

Existing analyses are opened using the Open icon in the toolbar:

Getting Started
The file extension for an existing analysis is .cfd. Make sure the Analysis bullet is
selected near the bottom of the dialog box.

The only time it is required to open an existing analysis from the CAD system is if
the geometry is from Pro/Engineer, AND you intend to construct a new mesh. Oth-
erwise, always open existing analyses by starting CFdesign from the Desktop or
Start menu, hitting the Open icon, and selecting the desired .cfd file. Note: if an
existing analysis is launched from the CAD system and run, a new mesh will be
generated, even if the mesh definition is not changed.

Projects

A project is a collection of analyses--in the same way an assembly is a collection of


parts in most CAD tools. Projects have two primary functions: to facilitate model
set up for similar analyses and to facilitate post-processing of similar analyses. Both
functions are described in Chapter 11 of this Guide.

CFdesign Users Guide


Getting Started

Note: An analysis is ALWAYS created from geometry--when CFdesign is launched


from a CAD tool, an analysis is always either created or opened. It is NOT possible
to go from a CAD system (or a Parasolid or Acis file) directly to a project.

A project can, however, be created or opened from within an open analysis


(thereby making the analysis a member of the project):

(3) Project

(1) CAD (2) Analysis

The opposite is also possible: an existing analysis can be imported into a project.

Project

Additionally, a project can be created or opened outside of an analysis by starting


CFdesign and hitting the New or Open icon, respectively, and selecting Project.

More information is presented in the Projects chapter of this guide.

The Basic Process

This section briefly summarizes the process of setting up, running, and visualizing
results with CFdesign. Starting CFdesign from various CAD systems with the direct
launchers and from the Desktop is discussed in a prior section. After the analysis is
named, the following general steps must be taken:
1. On the Feature Tree, set the Analysis Length Units system.
2. Using the Loads Task Dialog, apply boundary conditions and, if required, initial
conditions.
3. In the Mesh Task Dialog, apply mesh sizes to volumes, and if required for local
refinement, to surfaces and edges.

CFdesign Users Guide


Getting Started

4. Switch to the Materials Task Dialog, and apply materials to all parts in the
model. If necessary, create custom materials and add them to the Materials Data-
base.
5. If the analysis is to include moving solids, switch to the Motion task dialog, and

Getting Started
create and assign the motion to the intended parts.
6. Using the Options Task Dialog, select the physical model(s) to be used within
the analysis.
7. In the Analyze Task Dialog, input the number of iterations to run and the
Results Save Interval. Hit GO to start the analysis.
8. During the analysis, switch to the Results task dialog to view the results as they
are calculated. Use the Convergence Monitor to keep an eye on the solution
progress.
9. When the analysis is finished, use the Review task dialog to assess the final
convergence and to ensure that the solution is converged.
Switch to the Results task dialog to view the results.
Optional: add this analysis to a new or existing project. Return to the CAD sys-
tem and modify the geometry. Launch back into CFdesign, and create a new analy-
sis. Place this analysis into the project. Transfer the settings from the first analysis
to this one, and run it.

While this may seem like a lot of steps, the User Interface is designed to guide the
user through each, in the proper order. A separate icon controls each task dialog,
and these icons are arranged vertically on the side of the User Interface. By simply
starting at the top-most icon and working down, each task is performed easily and
logically.

CFdesign Client-Server

Introduction

CFdesign is built upon a client-server model. The user interacts with CFdesign
through the Interface Client (arenaqq.us). When the command to start the analy-
sis is given, a signal is sent to the Server (arenaqq.us) indicating that the analy-
sis needs to begin. The Server in turn sends a signal to the Solver (arenaqq.us).
This last step initiates the transfer of the model data from the Interface to the
Solver and then instructs the Solver to commence with the calculation. While the
analysis is running, the visual results are transferred from the Solver back to the

CFdesign Users Guide


Getting Started

Interface to provide for the Run-Time Results Display. When the analysis is com-
plete, the Server directs the Solver to send the final results back to the Interface.

On a stand-alone installation, this entire process is transparent to the user. After


hitting Go, the analysis runs, the analysis data files are kept in the users working
directory as the communication between the Server and the Interface and Solver
clients is managed automatically.

Fast Track

This client-server model allows CFdesign users to run analyses on a remote (net-
worked) computer. This kind of implementation is called Fast Track. The analysis
model is constructed and meshed on the local computer (using the CFdesign Inter-
face), but the actual calculation occurs on a remote computer. In this situation, the
Server directs the Interface to put the analysis model files physically on the remote
Solver computer for the calculation. When completed, the Server moves the files
back to the Interface (Users) computer.

Server Manager

For most installations, the Server is configured automatically during the installation
process. However, there is a dialog that controls the operation of the Server.
Located in the installation directory, this dialog is launched by clicking on serv-
arenaqq.us, and is shown:

CFdesign Users Guide


Getting Started

The Installation Directory is the CFdesign load point. The Analyze Directory, by
default, is a sub-directory within the CFdesign installation but can be any writable
directory on the local machine. This is where temporary files are written during the
analysis. The Install button registers the Server as a Windows service. This causes

Getting Started
the Server to start automatically every time the machine is started. The Installation
and Analyze Directory fields are set during the installation. They can be changed
manually, if necessary. Additionally, the Server is started for the first time during
the Installation.

If the Server must be stopped (such as when installing an update to the Server),
open this dialog, and click the Stop button. Be sure to start the service again after
the new file is in place.

Installing on a File Server Computer

Introduction

CFdesign can be installed such that the installation files reside on a file server
machine, and the User Interface and Solver run on users local machines. The
server process called CFD Server 9 runs locally and manages the communication
between the User Interface and the Solver (this is true for a single node installation
as well). In this type of configuration, however, the service (running on the local
machine) must run under an account that has read-only access on the file server
machine. Otherwise, the service will not have the necessary privileges to send com-
mands to the executable residing on the file server.

As part of every analysis, temporary files are written to an analyze directory


located on the users machine. Additionally, a small program (the Server Manager)
that configures and manages the server process must also be installed on each
users computer. A separate installation program (arenaqq.us) is
included on the installation CD that installs these items, and must be run on each
users machine. This is very quick, and installs the Server Manager, creates a local
Analyze directory, and creates the necessary environment variables.

Installation

As part of the software installation on the file server, be sure to check the Central-
ized File Server Install box in the Select Features dialog.

CFdesign Users Guide


Getting Started

After installing the software on the file server, create a domain user account for the
service. (This may require assistance from your Information Technology or Techni-
cal Support Group.) This can also be done between two machines within the same
workgroup by creating the same account on both machines. This account should
have read-write privileges in general, but can have read-only access on the file
server. Additionally, this account needs the Log On As A Service privilege.

On each users machine, as administrator, run the arenaqq.us found


on the Installation CD. This will prompt for:
A directory on the local machine where the analyze directory and the
Server Manager are to be installed.
The UNC path of the CFdesign network installation.
The account name and password of the service account.
If the service account is not automatically granted the Log On as a Service right,
then it may be necessary to manually perform the following steps on the client
machine:

Starting the Control Panel,


Go to Administrative Tools,
Select Services.
Click on the Cfd Server 9 service.
On the Properties dialog, click the Log On tab.
Click the This Account bullet, and enter the account login name and
password.
Click Apply.

Compatibility with CFdesign 8

Open your v8 analysis directly into v9. The settings should all migrate into the v9
format. Any settings that were lost due to changes in the Parasolid or Acis geome-
try kernels will be listed in the Lost List. This list is accessible by clicking the Show
Lost button on the appropriate dialog. If the Show Lost button is not visible, then
the migration to v8 did not incur any errors.

Note that for best results, the v8 analysis should be saved in the latest version of
v8. For Pro/E analyses, this means that the analysis should have been launched and
saved into the latest version of v8. Importing analyses from earlier builds of v8 may
result in a few lost settings.

The model is shown in the Graphics Region. The background color can be changed
using the Background Color tool button (described in the next section).

The File Tool Bar at the top controls file manipulation activities--Creating, Opening,
and Saving files. The Display Tool Bar controls the display of the interface and the
model. The Task Tool Bar controls which task dialog shows in the Task Dialog
Region. The Feature Tree lists the applied parameters, and can be used to modify
applied conditions (loads and mesh sizes). Additionally, it is used to control the dis-
play of individual parts and materials in the model, and to control the display of
results quantities.

The Menu Region contains commands for file manipulation and for setting prefer-
ences. The main Help menu is also in the Menu Region. The Task Dialogs contain
commands for setting up the analysis.

The default arrangement of the interface is shown in the above graphic. The display
and location of the Horizontal Tool Bar, the Feature Tree, and the Task Dialog
Region is customizable. To hide any of the entities, single click on the top bar of the
Task Dialog Region (or left side of the tool bars):

_Save Analysis As

Saves a copy of the current analysis to a new name and/or location. Note that the
newly created cfd file is opened, and the originally opened cfd file is saved and
closed.

Output_Support

Outputs a version of the cfd file that contains just the settings and the geometry,
but no mesh or results. This is a very small file, and is suitable for e-mailing to our
CFdesign Technical Support Engineers. Such a file has an _s appended to its
name.

Output_Results Share

A .cfd file containing the settings and results, but not the mesh. This is useful for
sharing your entire results set with someone else in the organization because it is
significantly smaller than the original cfd file. If the user opens such a file, they will
be able to view results, but not run. Hitting Analyze_Go will result in the mesh
being generated, and the solution starting back at iteration 0. Results Share files
have an _r appended to the original analysis name.

CFdesign Users Guide


The User Interface

Output_Archive

An Archive file contains the settings, mesh, and only the last saved results set.
This is useful for analyses in which numerous results or time steps were saved dur-

arenaqq.uss# or arenaqq.ust#) is saved. An _a file can be continued simply by
hitting Analyze_Go. This file is most suitable for archival purposes IF intermediate
result sets or time steps are not required.

_Export

CFdesign can write out the model and results in several formats for use in other
tools. Prior to Version 8, data was saved in these formats by setting a flag entry in

_Preferences_Settings Rules

Many analysis models are based on assemblies having multiple instances of the
same part. Every instance of the part typically has the same settings, and are used
repeatedly in numerous analyses.

This feature allows the automatic assignment of a volumetric boundary condition


and a material based on the part name. For many analysis models this feature will
greatly simplify and streamline the set-up process because it automates application
of key volumetric settings to a large number of parts, eliminating the burden of
having to apply a large number of settings manually. This feature should greatly
impact electronics cooling analyses in particular due to the large number of
repeated parts in electronic devices.

Rules defined with this dialog are automatically applied when an analysis is created
if the Apply box is checked. Rules are not automatically applied when an existing
analysis is opened.

Settings that can be applied as rules include volumetric boundary conditions and
materials that do not require any directional inputs in their definitions.

Settings rules are stored with other preferences in the cfdesignusr file. This file
is contained in the Documents and Settings\account\.cfdesign folder, where
account is the name of login account.

Boundary Conditions

Heat generation and Total heat generation conditions can be applied as settings
rules. Conditions can be defined as steady state or transient, and can be assigned
as temperature dependent. Note that temperature dependent conditions use the
temperature of the local part (and not a remote location) as the sensing location.

Materials

The materials available for application as settings rules are:

_Preferences_Results Units

Use this dialog to specify the default units of result scalars. In previous versions,
the units for any result scalar can be changed by right clicking on a scalar quantity,
selecting Units, and picking the desired unit system. Many companies have guide-
lines dictating how results are communicated internally, so in some cases, it was
necessary to always manually change the unit for displayed result quantities.

This dialog allows default units to be defined.

The units for each quantity are listed in the adjacent combo menu.

The choice Default is the first item for every quantity, and is shown if no unit sys-
tem is selected. Quantities with the Default selection are displayed using the
default units of the current units system.

The default units selected for a quantity will be applied to all related quantities as
well. For example, if the mm/h is selected as the default for velocity, then all veloc-

_Analysis Notes

When conducting design studies, keeping accurate records about each analysis is
very important, especially when comparing results from a large number of models.
Recording the specific conditions of an analysis, as well as any adjustments and
important findings, is key to repeatability and organization of a large project.

Every engineer has their own particular way of maintaining information about their
analysis models. Some use spreadsheets, some use notebooks, and some use

CFdesign Users Guide


The User Interface

scraps of paper. The CFdesign Notes file is a useful addition to the engineers
record-keeping tool-kit for, and is kept within the analysis file itself:

User Interface
Located in File_Notes, the Notes text editor provides a convienent way of record-
ing information about a particular analysis. The contents of the file are internal to
the analysis cfd file, so they can be easily accessed after the analysis is archived.
An external copy of the file can be saved by clicking the Save button.

Modifications made to the text file outside of CFdesign will not be accessible in the
CFdesign interface. This option is provided to save a copy of the notes to allow
quick access without having to open the cfd file.

_Print

A print utility has been added to the File menu to allow printing the image in the
Graphics window to either a file or to a printer. The background color is automati-
cally set to white, and text is shown as black for visibility.

CFdesign Users Guide

matically saved. If an analysis is running, the Exit command shuts down only the
Interface--the analysis will continue to run.

Help

The CFdesign Help System has been overhauled to make it much easier to use and
to provide a comprehensive set of information directly and conveniently to the user.
The complete documentation set has been integrated with the CFdesign product,
and is accessed on a context-sensitive basis using the Help button on every dialog

User Interface
in the Interface. The complete manual set is also accessible from the Help menu
item from the Main Menu.

All manuals are packaged in Adobe pdf format. The Adobe Acrobat Reader is
included with the CFdesign interface, and is opened when Help buttons or items in
the Help menu are selected. The manuals can also be viewed outside of CFdesign
using Acrobat Reader. Note that the documentation is fully indexed, and includes a
table of contents. Acrobat Reader includes full search capability as well.

Most dialogs in the CFdesign User Interface contain a Help button. Pushing a Help
button opens the Users Guide to the appropriate location to describe the relevant
dialog or function.

_CFdesign Help Topics

Opens the Users Guide in Acrobat Reader. The Guide is fully indexed, and includes
a table of contents. Links within the document connect sections and chapters where
appropriate.

_On-Line Tutorial

Opens the CFdesign Examples Guide. Presented in Acrobat Reader, the Guide has
been formatted so that it can easily be positioned adjacent to the CFdesign inter-
face while working through the examples. This is a convenient resource for learning
how to operate CFdesign.

_Licensing

This item brings up a dialog that shows the current license status. This is a very
useful tool for troubleshooting license problems. The dialog indicates which license

CFdesign Users Guide


The User Interface

server the software is looking to for a license. It also indicates the number of Inter-
face and Solver licenses available.

The Preferences button brings up a dialog that allows selection of a specific func-
tionality level if the floating (network) license contains a combination of different
functional levels.

To provide a high level of flexibility in licensing for larger installations with network
licenses, CFdesign includes the ability to check out a specific funtionality tier from a
mixed pool of licenses.

For example, if a corporate site-license includes four Advanced licenses and one
Motion license, this function allows the user to select a Motion license only when the
Motion functionality is required. For analyses that do not include solid-body motion,

User Interface
the user would select an Advanced license. This would leave the Motion licenses
available for other engineers that do need the Motion capability.

For a heterogeneous CFdesign license (a license that contains seats with different
funtionality levels), the License Preferences dialog will pop up automatically when
CFdesign is started:

This dialog lists the licenses that are available, and prompts the user to select
which type of license they will use. If, for example, Advanced is selected, then the
Motion functionality will be unavailable in the CFdesign interface. If Motion is
selected, the Motion license is checked out, and the Motion functionality will be
available. (Note that Motion includes the advanced functionality set as well.)

CFdesign Users Guide


The User Interface

By default, this dialog will appear every time CFdesign is started. Uncheck the
check box to make the setting permanent (and to prevent the dialog from display-
ing every time). To change the setting simply click Help_Licensing_Preferences.

For node-locked licenses and homogeneous network license (meaning that all of
the seats are at the same functionality level) the License Preferences dialog does
not appear. No input is required for such a license installation.

The User Interface

Entity Selection

The selection mode (on the Loads and Mesh dialogs) controls which type of entity is
selectable: volume, surface, or edge.

Selection Mode
Selection Basis

The Selection Mode can be changed on the Loads and Mesh dialogs, but on Mate-
rials, it is set to only Volumes or Surfaces (3D or 2D models, respectively).

The Selection Basis allows for associative selection and the selection of groups.
Associativity is based on geometry, and provides a quick way to select multiple
entities that are related to the Selection Basis type (surfaces owned by a volume,
for example). Entities of the type shown in the Selection Basis menu will highlight
as the mouse is moved over them. When picked, all of the items of the current
selection mode that are associated with the picked item will be selected. Groups will
be discussed later in this chapter.

The Selection Basis modes for each selectable entity are:

Entity Selection Basis


Volume Direct -- Volumes are highlighted and are selected
By Material -- All volumes that have the same material
are highlighted and selected together.
Surface Direct -- Surfaces are highlighted and are selected
By Volume -- Volumes are highlighted, and all surfaces
touching a picked volume are selected.
Edge Direct -- Edges are highlighted and are selected
By Surface -- Surfaces are highlighted, and all edges
touching a picked surface are selected.
By Volume -- Volumes are highlighted, and all edges
touching a picked volume are selected.

CFdesign Users Guide


The User Interface

The four buttons adjacent to the Selection Basis drop menu simplify selection and
deselection of multiple entities:

Select All entities


Select Previously selected entities
Deselect highlighted
(in the Selection List) entity Deselect All selected entities

When the mouse hovers over an entity, it turns green. When an entity is selected,
it turns red. When the mouse hovers over an already selected entity, it turns yel-

User Interface
low.

To deselect an entity, simply click on it again, or highlight it in the Selection List


and hit the Deselect button.

To be selectable, an entity must not be occluded by another entity. If there is an


entity blocking the line of sight to the desired entity, use the right mouse button to
blank its display (see the next section).

When an item is selected, its label is shown in the Selection List. Multiple selected

items can be highlighted in the list using the Windows standard selection meth-
ods--hold down the control key while clicking on items to select multiple items;
hold down the shift key while clicking on items to select a range.

CFdesign Users Guide


The User Interface

Entity Visibility

Blanking

An entity can be blanked by right clicking the mouse on it. Only entities of the type
in the current selection mode will be blanked. To redisplay all blanked entities, right
click the mouse somewhere off of the model. Shown is a model with some surfaces
blanked. Note how the surface underneath is now visible, and therefore pickable.

Blanking entities is very useful when applying boundary conditions and mesh sizes
to allow easy access to objects in the background.

Blanking Undo

Clicking the middle mouse button in Mouse Mode 1 (which is also the scroll wheel
on some mouse devices) will undo blanking commands in the opposite order that
they were issued. Use the Ctrl+Middle mouse button in Mode 2. In Mouse Modes 3
and 4, undo blanking with the Ctrl+Right mouse button.

This action will also undo the redisplay of all hidden entities. If the user had blanked
several parts in an effort to gain access to an internal part, but accidently redis-
plays the entire assembly, they now can simply hit the middle mouse button, and
undo the redisplay command.

The User Interface

Feature Tree

The Feature Tree has several functions that assist in setting up and running a CFde-
sign analysis. Some of the branches allow certain analysis settings to be made.

User Interface
Other branches list existing settings, and allow them to be modified easily. Most of
the branches will be described with their relative chapters (the Boundary Conditions
and Initial Conditions branches will be discussed in the Loads chapter, for exam-
ple). This section describes the branches that are specific to the Feature Tree, and
are not associated with a Dialog Task.

Units

When an analysis is created, the default units system will be meters (unless the
default was changed using File_Preferences).

For Pro/Engineer and CATIA v5 geometries, changing the units system only
changes the analysis length unit--it DOES NOT convert any dimensions in the
model.

For geometries originating in other CAD systems that are Parasolid or Acis based,
the Units branch works slightly differently. Because most CAD systems output
geometry in meters (converted from the working units system), CFdesign will set
the analysis units to meters, when it reads in the geometry file. Unless the geome-
try was originally built in meters, the model will have different dimensions in CFde-
sign than in the CAD system. To convert the units system, simply select (left

CFdesign Users Guide


The User Interface

click on) the desired units system from the Length Units branch of the Fea-
ture Tree.

To make this process easier, it is recommended that you set the default units
system in File_Preferences to the working units system in your CAD sys-
tem. When geometry is read into CFdesign for a new analysis, the analysis units
system will automatically be set, and the length dimensions of the model will be the
same as in the CAD system (they will be automatically converted from meters to
the default units system during the import).

When reading in a geometry file and the dimensions are correct but the unit
system is not, change just the units system (without changing any model dimen-
sions) by right clicking on the desired unit system, and selecting Change Length
Unit Only. This is applicable if the CAD system does not convert the units to
meters when exporting geometry. Autodesk Inventor behaves this way.

Coordinate Systems

For three dimensional analyses, Cartesian (XYZ) is the only available coordinate
system.

For two dimensional analyses, the choices are Cartesian and Axisymmetric about
the X and Axisymmetric about the Y.

A two dimensional Cartesian geometry is always assumed to have a unit depth.

An axisymmetric geometry is a three dimensional geometry that is uniform in the


tangential direction. Because of this uniformity, a single slice through the geometry
can be simulated as a two dimensional model. The nice thing about axisymmetric
modelling is that a two dimensional analysis can give correct results for a three
dimensional model. An example of axisymmetric geometry is a straight pipe.

It is recommended that axisymmetric geometries be constructed in the first quad-


rant. Geometries that are axisymmetric about the x-axis cannot cross the x-axis
because the x-axis is the center-line. Likewise, geometries that are axisymmetric
about the y-axis cannot cross the y-axis. A unit radian depth is always assumed for
axisymmetric geometries.

The User Interface

Parts

Every part in the CAD model will be listed as a branch in the Parts section. The main
function of this branch is to set individual part view parameters and to allow selec-
tion of parts.

Left click on a part to highlight its display.

Right click on a part to bring up a menu with the following items: Select, Outline,
Transparent, and Add to Group.

Select a part from the Parts or Materials branch of the feature tree by right clicking
on its entity label and picking Select from the menu. Use the Windows standard
(shift or ctrl keys) to select multiple parts.

User Interface
In Analyze (during the run), Review, and Results modes, the Parts branch is not
displayed in the Feature Tree. Individual part display attributes are set using the
Materials branch.

Naming Entities with Assigned Conditions

Geometric entities with assigned conditions can be renamed in the Feature Tree.
This feature is applicable to surfaces and edges for 3d models and edges for 2d
models that have boundary conditions, initial conditions, or mesh sizes. (Note that
part names cannot be changed within the CFdesign interface.)

CFdesign Users Guide


The User Interface

To change the name of an entity, right click on the current name in the feature
tree, and select Change Name. Enter the new name in the dialog that appears,
and hit OK. The entity will be renamed in the feature tree, and the name will persist
in other branches of the tree if other settings are applied to the entity.

Groups

Introduction

Geometric entities such as volumes, surfaces, or edges can be grouped based on


part name, material, common mesh size or boundary condition. Groups of entities
can then be selected with a button click to add additional settings. Groups of sur-
faces can also be selected for assessing wall results (post processing).

A Group is a homogeneous collection of entities: volumes, surfaces, or edges. A


group cannot contain a combination of entities (such as a mixture of volumes and
surfaces, for example).

CFdesign Users Guide


The User Interface

Creating Groups

Create a group by right clicking on the


main Group branch in the feature tree,
and select Create Group

A dialog will come up prompting for a


group name. To group geometric enti-
ties (parts, surfaces, edges), select
Geometric as the Type.
To group parts by Motion (for linked
motion), select Motion as the type.
(This is described in the Motion chapter

1. Parts can also be added to an exist-


ing group by right clicking on a group
name, and selecting Add by Name.
2. Use a regular expression to type in
part of the name that is common to the
parts to be added to the group. (Be sure
to check the Regular Expression box.)

For example, to add multiple parts with


the word chip in their name, enter
*chip*, and all parts that have the
word chip somewhere in their name will
be added to the group.

Loads
Boundary conditions and initial condi-
tions are applied with the Loads Command
Dialog.
Items such as velocity, pressure, and tem-
perature are applied to the surfaces of a
model (to edges in 2D models).
Volumetric heat generation and total heat
generation are applied to volumes (to sur-
faces in 2D models).
Select the units for each boundary and initial
condition type.
Transient (time-dependent) boundary condi-
tions are also applied and defined in the
Loads task.
Please see the Loads chapter for more infor-
mation.

Mesh Sizes
A mesh has to be constructed which
divides the entire geometry into small
pieces, or elements.
Each element has four nodes, one at each
corner. The finite element equations are then
solved at each node in the model.
This dialog provides tools to automatically
define a mesh as well as identify potential
problem areas within the geometry.
The Mesh Enhancement parameters are
adjusted by clicking the Mesh Enhancement
button.

Additional Parameters (Flags File)

There are some additional parameters that control output of optional files as well as
provide additional control to the way geometry is handled. These parameters must
be in a file called cfdesign_arenaqq.us, which is located in the installation directory.
The default location of the file is the CFdesign installation directory. An environment
variable called CFDESIGN90TEMP must point to the location of this file.

This file can be moved to a different location, but the environment variable must be
updated to point to the new location.

The variables in the flags file, their parameters, and their meanings are shown:

CHAPTE R 3 Geometry

Introduction

CFdesign has very strong ties to most of the CAD tools used in industry today. By
using the same geometry engines found in these CAD systems, CFdesign reads the
native model without the need for Step or IGES translations. Parametric changes to
the geometry are read directly into CFdesign, and model settings from similar anal-
yses are automatically applied to the modified geometry.

This functionality allows two things to occur very easily: The first is that multiple
design alternatives can be analyzed very easily--without having to go to great
lengths to fix IGES or Step translations for each what if scenario. The second is
that corporate PLM/PDM initiatives are supported--geometry manipulation occurs
ONLY in the CAD system, where it can be tracked and archived. When geometry is
manipulated in a third party system (such as many of the other CFD tools),
changes often get lost, or simply have to be re-created in the CAD system--thereby
doubling the work. With CFdesign, such issues are not a problem.

This chapter describes the type of CAD geometry needed to successfully run a flow
analysis. Guidelines for what is needed, techniques for how to obtain it, and trou-
bleshooting tips are presented. Guidelines specific to Pro/Engineer and to Parasolid/
Acis based CAD systems are discussed.

What is Flow Geometry?

Geometry used for a typical fluid flow analysis is often different than that used in a
structural analysis. There are two broad classifications of flow geometry: internal
and external. Examples of internal flows include pipe flow, valve flow, and flow in
electronic enclosures. Examples of external flows, also called submerged flows,
include flow over a car, an airplane wing, or a missile.

CFdesign Users Guide


Geometry

For internal flows, a flow core must be created from the existing surrounding
geometry. The outer walls of the volume are omitted (unless they are to be used as
part of a heat transfer calculation) and the interior volume of the pipe is modeled.

In contrast, in a structural analysis the walls of the pipe would be meshed and the
interior would be omitted from the calculation domain:

Another description of the interior volume is this: a pipe is filled with water and the
water is allowed to freeze. Now, imagine that the pipe walls are removed, and all
that remained was the solid volume of ice. This volume is where the fluid exists,
and is the geometry that would be created and meshed for a CFD analysis of flow
through that pipe.

For external flows, it is customary to invert the geometry, meaning that the
object will be made stationary and the flow will be blown over it at the equal and
opposite speed of the object. To implement this as analysis geometry, two pieces of

CFdesign Users Guide


Geometry

geometry are needed: the object itself (missile, car, bullet, etc.) and a large calcu-
lation domain in which the object is positioned:

Geometry
The shape of the domain is usually not very critical, and can be a circle, semi-circle,
rectangle, sphere, or box. Because the flow all around the object is being modeled,
it is a good idea to make the computational domain substantially larger than the
object itself. More detail about the relative size of the calculation domain will be dis-
cussed in Chapter 12 of this Guide.

Pro/Engineer

This section discusses geometry considerations specific to Pro/Engineer.

Automatic Flow Volume Creation in Pro/E

Many models constructed in Pro/E consist of just the physical solids (the pipe wall,
for example). In earlier versions of CFdesign, it was necessary to manually create
the flow volume in Pro/E. To reduce the amount of time and effort needed to pre-
pare a Pro/E geometry for analysis, CFdesign has the ability to convert a fully
enclosed void into a meshable volume.

Applying Void Filling

In the following example, the pipe wall and two internal parts were created in Pro/
Engineer:

CFdesign Users Guide


Geometry

To prepare this for a flow analysis, simply add a cap to both ends of the pipe:

The Pro/E geometry shown above consists of five parts: the pipe wall, the two
internal components, and the two end caps. In this example, the caps are con-
structed using the inner diameter of the pipe wall, and extruded into the pipe.
Alternatively, the caps could have been extruded out of the pipe, or have been built
using the outer diameter of the pipe wall.

When brought into CFdesign, the internal volume is automatically created:

Geometry

The two internal parts are automatically cut from the newly created flow volume.

Geometry

Invoking Void Filling

Pro/E Void Filling is enabled by default. To deactivate it, make the following entry in
your cfdesign_arenaqq.us file. A value of 1 activates fill voids, a value of 0 disables it:

PROTOOL FILLVOIDS 0

The cfdesign_arenaqq.us file can be placed anywhere on your local computer. Be sure
to set an environment variable called CFDESIGN90TEMP to point to the location of
your flags file. Its default location is in the CFdesign installation directory.

Guidelines

Components built in Pro/E must not interfere, so care must still be taken to elimi-
nate part interferences from the Pro/E model.

There are a few guidelines that should be observed or the automatic void creation
will not work:
Parts that are inside of the void must not protrude through the outer
wall of the geometry. If this occurs, the void filling will fail. This is shown:

Part must not protrude


through end cap

CFdesign Users Guide


Geometry

End caps must not extend beyond the geometry surrounding an open-
ing. In this pipe example, the cap must not extend beyond the outer diam-
eter of the pipe. An example that will fail is shown:

End cap extends beyond outer


edge of geometry.

This will NOT produce a flow


volume.

Volume and Surface Regions

There are situations in two and three dimensional geometry where it is advanta-
geous to divide a surface or volume into smaller areas. This is especially useful for
boundary condition placement, and sometimes for greater control over mesh den-
sity. In Pro/E, create a surface region to divide a surface into smaller surfaces or a
volume region to divide a volume into smaller volumes. CFdesign will read in these
divisions, and allow boundary conditions and mesh definitions on the new surfaces

Geometry
and edges.

CFdesign Users Guide


Geometry

An example in Pro/E is shown:

The procedure to create a surface region follows (volume region creation is simi-
lar):
1. Click on Applications_Mechanica.
2. On the Mechanica menu, select Structure.
3. Select Model_Features_Surf Region_Create. At this point, click either
Sketch to sketch the region, or Select if datum curves already exist which define
the region. Click Done.
4. If Sketch was selected, you will be prompted to select a sketch plane and to
orient it.
5. You will then be in Sketch mode. Draw and dimension the region.
6. After completing the section, you will be asked to select the surface(s) to be
split. Do so, then hit Done Sel and Done.

Note that your Pro/E license must allow access to the Mechanica FEM mode to use
Simuation Features.

When CFdesign is started, you will see the region as another surface.

Two Dimensional Geometry

Often two dimensional geometry is useful for simulating axisymmetric geometry or


for a simply first crack at an analysis. To create a two dimensional feature, do the
following:

CFdesign Users Guide


Geometry

1. Click Feature_Create_Surface_Flat.
2. Position the drawing (the XY plane is the recommended orientation).
3. If the geometry is an axisymmetric model, be sure to position it relative to the
x or y axis properly. If the geometry is axisymmetric about the x axis, it cannot
cross the x axis. If it is axisymmetric about the y axis, it cannot cross the y axis.
We recommend that axisymmetric geometry be constructed in the first quadrant of
the coordinate axis.
4. Proceed into CFdesign exactly as you would for a three dimensional model.

Interferences

When working with assemblies, it is very important in Pro/Engineer geometries that


no parts interfere (take up the same volume). If two or more parts do interfere, the
mesher will fail.

Very often there are parts that are physically inside other parts. Care must be
taken to ensure that internal parts are first cut out of surrounding parts, and that
they do not interfere. On the screen it may appear that the model is correct simply
by placing a solid inside another (thats what one would do physically!), but in Pro/
E, it is necessary to first cut out internal solids from the surrounding air. Once that
is done, the internal part and the surrounding parts do not interfere.

Geometry
Shown is an example of two parts that interfere

To check for interference in Pro/E, do the following:


1. From the Pro/E main menu, click Analysis_Model Analysis.
2. Select Global Interference from the Type menu.
3. Hit the Compute button.

CFdesign Users Guide


Geometry

Any parts that interfere will be highlighted. To fix an interference, it may be neces-
sary to move one or more parts, cut one part from another (see Section ), or
to delete parts. Every model is different, so the solution will be dependent on the
goal of the analysis. Shown are a couple of examples of fixed geometry:

Accuracy

When working with assemblies, it is recommended that all the parts in the assem-
bly (and the assembly itself) have the same absolute accuracy. In many cases, it
might not matter, but if you try to launch into CFdesign, and both Pro/E and CFde-
sign crash, you should adjust the accuracies of the parts and assemblies in your
model.

By default, absolute accuracy is not enabled in Pro/E. To turn it on, a configuration


setting called enable_absolute_accuracy needs to be set. To do this:
1. From the Pro/E main menu, click on Utilities_Preferences.
2. Click on the Find button, and search for the keyword accuracy. Select
enable_absolute_accuracy, and change the value to Yes.

To set the absolute accuracy for the parts and assembly, first find out what the
absolute accuracy is for the smallest part, then change the absolute accuracy of the
other parts to that of the smallest:
1. Open the part, and click on Setup_Accuracy (from the Part or assembly
menu).

CFdesign Users Guide


Geometry

2. Pro/E will prompt for a relative accuracy, so click the ESC key, and select Abso-
lute Accuracy.
3. Select Absolute, and Enter Value, and enter the value for absolute accuracy.
4. Click the Check mark, and the part will regenerate.

Modifying the part and assembly accuracy to absolute is not always necessary, but
if there are parts with very small features and larger parts in the same assembly, it
can be very useful for preventing crashes.

Also, if automatic void filling is enabled but fails to create the internal volume
(assuming that the guidelines in the void filling section of this chapter are fol-
lowed), it may be necessary to modify the accuracy on the parts and assembly to
be absolute. If the void filling still fails, using a smaller accuracy value might correct
the problem.

When using simulation volume regions (particularly in Wildfire), if they do not


appear as a separate volume from the surrounding part (in CFdesign), then setting
the accuracy to absolute (and then using a smaller value if necessary) will often
cause the volume region to be considered as a separate part.

When Pro/E Must be Running

For a new analysis, CFdesign MUST be launched from Pro/E. When you do this, you
will see that Pro/E minimizes, and is in a sleep state. You will also notice that

Geometry
when you hit the GO button on the Analyze window in CFdesign, Pro/E comes back,
but is working. The mesh is actually being generated by CFdesign by reading the
part geometry from the Pro/E database. It is accessing the part and assembly infor-
mation in the same way that Pro/Mesh accesses it. For this reason, CFdesign must
be launched from Pro/E when the goal is to generate a mesh.

Once CFdesign returns, the analysis proceeds automatically. Pro/E returns to a


sleep state, and cannot be accessed. To access Pro/E, do one of the following:
1. Set the number of iterations to 0, so that after meshing and pre-processing, the
analysis does not proceed. Exit out of CFdesign, and then exit out of Pro/E. Start
CFdesign from the Desktop, open the analysis, and run it.
2. While the analysis is running shut down the CFdesign interface. (The analysis
will continue to run.) After the interface is shutdown, Pro/E can be accessed or shut
down as required.

CFdesign Users Guide


Geometry

If a mesh exists, and if the goal is to do anything (modify boundary conditions,


materials, run more iterations, view results, etc.) other than generate a new mesh,
CFdesign can be started from the Desktop or Start Menu. Open the .cfd file.

Split Surfaces in Pro/E

When a three dimensional part is divided by another part into multiple volumes, the
result will be split surfaces. The problem with split surfaces is that they are con-
sidered by the Pro/E model to be a single surface (even though there are discon-
nected). When a boundary condition is applied to one of these surfaces, it may be
lost or will jump to the other surface when the analysis is saved. An example is
shown:
Original part, divided by an
Original part additional part.

Two surfaces, but considered


to be the same by Pro/E. Settings
applied to one surface may be lost
jump to the other.

An easy fix is to add a protrusion or cut feature to one of the volumes so that the
surfaces are unique. This will prevent conditions from jumping or being lost.

Parasolid and Acis Based CAD Systems

This section discusses geometry issues that are specific to the Parasolid and Acis-
based CAD systems. Such systems include Inventor (Acis), Solid Edge (Parasolid),
Unigraphics (Parasolid), Solid Works (Parasolid), Solid Designer (Acis), and CAD-
Key (Acis).

Geometry

The Internal Flow Volume

The internal flow volume will be created by CFdesign provided that the internal vol-
ume is completely enclosed. This means that when the open ends of an internal
flow geometry are capped with either a surface or volume and then read into CFde-
sign, the internal core will be generated automatically. This is illustrated below:

Step 1: Pipe geometry--only the physical solids exist (pipe wall and poppet):

Step 2: Pipe geometry with newly-created volumes at the ends (pipe wall, poppet,
and two end caps). The end caps were created by extruding the inner-radius curves

Geometry
of the pipe. This extends the flow volume slightly, but they can be omitted from the
meshing if necessary.

CFdesign Users Guide


Geometry

Note: For Acis geometries, it is recommended that the end caps be larger than the
ends. The following graphic shows this:

Step 3: Geometry read by CFdesign--the flow core has been created automatically,
and is shown as the highlighted volume. Notice that there are now five volumes
listed in the Materials branch of the Feature Tree--the pipe wall, the poppet, the
two end caps, and the flow volume.

If there are objects inside of the flow volume (like a poppet for example), they will
automatically be embedded into the flow volume. This means that it is not neces-
sary to cut out submerged objects from their surrounding geometry.

For Solid Works-based analyses, if a geometric change is made to an existing anal-


ysis model such that the topology of an internal core volume is changed, the vol-
ume settings (volume mesh size and material definition) will be lost from that core
volume. Such a change would be the addition or removal of a part or features of a
part that are inside the void. The reason for this is that core volumes are not cre-
ated in the CAD tool, they are created by CFdesign when the geometry is read in.
Because of this, there is no direct geometric link between the core volume and the
original CAD model. Settings on geometric entities created in the CAD tool will be
preserved for most topological changes, however.

If it is not necessary (or desirable) to mesh various solids in a model (the pipe wall
and poppet, for example), then a no-mesh condition can be applied to them during
the mesh definition step. (This is covered in more detail in the Meshing chapter). In
the preceding example, because the flow volume was created based on the solid
geometry, the poppet is cut out from the flow volume, and fluid will not pass
through this region even if the poppet is not meshed.

CFdesign Users Guide


Geometry

Submerged Objects and External Flows

Many analysis models are built have physical solids that are submerged in the flow.
Such objects are often involved in a heat transfer analysis, and may carry a heat
load. The method for dealing with submerged objects is very simple: Place them in
the desired location within the surrounding volume. It is not necessary to remove
interferences or to cut an internal part from the surrounding volume. CFdesign will
do this automatically. The following graphics illustrate this.

Step 1: An empty box representing the air in an electronics box.

Step 2: Components are simply placed inside the box in the appropriate locations.

Geometry

Step 3: As the model is read into CFdesign, the components are automatically cut
from the air to remove all geometric interferences. Proper connectivity between all
contacting parts is automatically ensured.

CFdesign Users Guide


Geometry

In our example, the air volume in the CAD system was only a box. As CFdesign
read the geometry, voids for the internal components were cut into the air. This is
why the internal curves highlight when the air volume is selected.

This applies to both internal flows with submerged objects (examples include valves
with poppets and electronic packages), and for external flows simulating the flow
over a moving object. To include the obstruction as a meshable volume in the anal-
ysis model, simply place it in the surrounding volume at the desired location.

Two Dimensional Geometry

Often two dimensional geometry is useful for simulating axisymmetric geometry or


for simply an initial attempt at an analysis. A Parasolid or Acis surface in the XY
plane is necessary for such an analysis.

Axisymmetric geometries must be constructed relative to the x or y axis properly. If


the geometry is axisymmetric about the x axis, it cannot cross the x axis. If it is
axisymmetric about the y axis, it cannot cross the y axis. We recommend that axi-
symmetric geometry be constructed in the first quadrant of the coordinate axis.

Part Names

Part names assigned in Parasolid- and Acis-based CAD tools will now appear in the
CFdesign feature tree. Only part names are listed in the Parts branch of the feature
tree; assemblies are not listed.

From Solid Works, the naming convention of a part is based on the parent assembly
and any parts that surround that part. For example, a part called small-chip is a
member of a sub-assembly called left-board_asm. This part is also surrounded by
a part called test-box. The part name in the feature tree would then be:

TEST-BOX_U_SMALL-CHIP-4@LEFT-BOARD_ASM

The U indicates that the part SMALL-CHIP is surrounded by the part TEST-BOX.

If a part is used multiple times in an assembly, an instance number will be attached


to the part name. In the example above, this part was the fourth instance of the
part SMALL-CHIP.

CFdesign Users Guide


Geometry

If the geometry was not launched from Solid Works, the part names will be a com-
bination of the CAD part name and any part that completely surrounds it. The name
of the part listed above would be:

TEST-BOX_U_SMALL-CHIP^4

In some cases, the actual part name (without the surrounding part or assembly)
will be listed in the feature tree. This is typically because the part is surrounded by
an automatically-created flow volume.

Note that internal core parts that are created by CFdesign will be assigned the
generic name volume. This is because such parts were not created in the native
CAD tool, and hence did not have a name. Also, the name of internal core parts will
not be used within the names of other parts they completely surround.

CATIA V5

The CFdesign interface for CATIA is designed to work with V5R14, V5R15, and
V5R This is an associative interface that reads the geometry directly from the
CATIA database--it does not rely on file translations. Meshing is performed by
CFdesign directly on the CATIA geometry.

After launching CFdesign from CATIA, the CATIA interface will minimize (but CATIA

Geometry
will continue to run). The CFdesign interface will start, and will prompt for an anal-
ysis name. The analysis model is then set up according to standard practices out-
lined in the CFdesign documentation. When the analysis is started (by hitting the
GO button on the Analyze task) the CFdesign interface will minimize and the CATIA
interface will reappear. Meshing status messages are written to the Status bar in
the CATIA interface. After meshing is completed, the CFdesign interface will reap-
pear, and the analysis will continue.

Part Names

The names assigned to CATParts remain with them when the model is brought into
CFdesign.

CFdesign Users Guide


Geometry

Interferences

Interferences between CATIA geometry are not supported in the CFdesign inter-
face. Please ensure that all interferences are removed before launching into CFde-
sign. The result of not removing them is likely a crash either when CFdesign is first
launched or when the mesh is generated.

PART 1 IMPORTANT POINTS FOR THE GUIDANCE OF THE FIRMS / CONTRACTORS WHO ARE INTENDING TO SUBMIT TENDERS 1. Usually the firms/ contractors are prone to include number of conditions in the offer, such conditional offer being liable for rejection. The tenderers are therefore, advised to submit the tenders without their own conditions. In case, due to economic and technical considerations if they consider some conditions are necessary, they are requested to give clear cut financial implications of each of such conditions to facilitate proper evaluation and cost loadings of such effect in appropriate envelope. 2. No price escalation shall be payable except under Force Majeure conditions and as per formula given under Para of Detailed Notice Inviting Tender. 3. The tenderers are required to see that their tenders are in conformity with the conditions and clauses of the N. I.T. (Notice Inviting Tender) and the contract agreement form, particularly in regard to security deposit, mode of payment for extra work, if any, completion time, guarantee about mechanical and electrical equipments & water tightness, tests, structure stability etc. for entire Civil works. 4. Since the tender is on turnkey job basis, no advance payment towards the mechanical & electrical equipments, items will be considered. 5. The firms/ contractors sometimes ask for the refund of security deposit in a manner and time not in conformity with the provision of the N. I. T. Any such condition will not be in the interest of the Madhya Pradesh Jal Nigam Maryadit as such tenderers are requested to agree to the condition No. of the Part III of the detailed NIT. 6.
