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

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

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
