Introduction to ANSYS DesignModeler

DesignModeler

What will you learn from this presentation:

Direct Modeling Vs History based modeling

Process for preprocessing using ANSYS tools

How to launch DesignModeler?

DesignModeler interface



December 2010





Modeling Methods

Feature/History based Modeling

• CAD like approach to create new models

with sketch-to-3D operations

Direct Modeling

• Import models from CAD and perform

various geometric operations to prepare it

• Import models from CAD and performvarious geometric operations to prepare it

for meshing

• Locally parametric• More flexibility to make unplanned and local

changes

• Fully parametric

– Captures engineering intent

– Supports native CAD parameters

– Drives chan es b chan in a few

– No features + no constraints = no

regeneration failures

– Easy to edit “dumb” neutral files

– Easy to repair, prepare and optimize models

parameters in an automated way

• Feature tree

– Maintains history of all features

for analysis

• Analysis focused

– Custom tools to repair, prepare and optimize

models for analysis

– Custom tools to repair, prepare and optimize

models for analysis

• ANSYS Design Modeler

• GAMBIT (legacy ANSYS product), ANSYSSpaceClaim

Launching DesignModeler

From Component Systems

Ex: Geometry, Mesh

From Analysis Systems

Ex: Fluid Flow (Fluent), Fluid Flow (CFX)



December 2010

DesignModeler cannot be launched in a standalone mode, it can be only launched within

Workbench as shown in the above example





Set up Working Units

• Unit selection menu pops up

immediately after DM launches

• Always use project unit : Project unitsset in Workbench will be used

•

selected from the panel will be used

• Enable large model support : enable

bounding box of 1000 cubic km.

DM will no longer show the Units pop up panel in subsequent DM sessions if ‘Always

‘ ‘ ’



December 2010

.

Units cannot be changed mid-session





Basic Mouse Control

– LMB

• Geometry selection

• a s removes se ec e en es

• Hold LMB and sweep cursor = continuous selection

– MMB

• Rotate

• Shift + MMB : Zoom

– RMB

• Box Zoom

• Open context menus

Tricks on ‘Selection’

• To select multiple entities, drag the mouse to

create a box enclosing the entitiesSelect Mode –

Select single entity

Select multiple entities

Hash lines on the edges of box help to

determine the type of selection

1. Rotate : For dynamic rotation of the object2. Pan: To scroll the object around

4. Box Zoom: Zooms to the view enclosed by the box created by dragging the LMB

5. Fit Model to Screen: Zooms in to fit the full model in the screen.

7. Previous View: Works as Undo for the Displays

8. Next View: Works as Redo for the displays

More Details on Mouse Control

• Rotate Behavior (LMB):

– Cursor outside center :

Rotation about Z view

– Cursor near center of graphics screen :

Free rotations

– Cursor near edge of graphics screen :Rotations about X (top/bottom) or

Y (left/right) axes

– While in Rotate, Pan, or Zoom mode:

• Left click on model: resets center of

view and rotation at cursor location

(identified by red dot)

• Left click in open area re-centers
