Single Physics/Multi Physics
Single physics is the
entry point to
Fluid Pressure
Simulation
Distribution
Multi-Physics enables
real virtual prototyping
Stress ?

Robust Design Tools at ANSYS
•
ANSYS DesignXplorer
– Unified Workbench solution
•
ANSYS Fluent
– Built-in Mesh Morphing and
shape Optimization (MMO) tools
Baseline Design
• Being hooked up to DX for 14.5
–– AAddjjooiinntt ssoollvveerr
Optimized Design
High sensitivity – changes to
shape have a big effect on drag
High sensitivity – Shape on
Downforce
Low sensitivity
