Getting your CAD geometries ready for FEA modeling is easier than ever with the CAD Import Module. It facilitates the reading of industry-standard formats such as STEP, IGES, ACIS® (SAT®) or Parasolid®. Extra add-ons support file formats for packages that have their own geometry kernel.
The CAD Import Module goes beyond just the reading of file formats. The interactive repair feature assures that imported geometries are mathematically correct for FEA modeling. And, in order to cut down on unnecessary details in your CAD geometries, defeaturing tools that remove fillets, small faces, sliver faces, as well as spikes or short edges are included.
The CAD Import Module also provides a bidirectional interface to SolidWorks® that maintains associativity with the CAD system. This means that parameters can be changed in COMSOL models, which result in automatically updating the CAD geometry in SolidWorks that then updates the COMSOL geometry for a new model.
