Import from Autodesk Inventor to Ansys DesignModeler

Geometry created in Inventor rarely arrives ready to simulate. What a CAD model describes is the solid part; what a CFD case needs is the volume the fluid occupies, and often a simplified version of the solid around it.

There are two ways in. The associative link keeps DesignModeler connected to the Inventor file, so changes in the CAD propagate to the analysis, which is convenient while a design is still moving. A neutral format such as STEP or Parasolid breaks that link but avoids version and licensing issues, and is usually the more predictable route.

Whichever you choose, the work starts after the import: suppress the details that do not affect the flow, such as small fillets, threads and fasteners, then build the enclosure and subtract the solid to obtain the fluid domain.
