LiveLink™ for Revit® enables modeling using 3D designs synchronized from the Revit® building design software. The included user interface builds on an associative transfer of the geometry from the CAD program to the COMSOL model.

If you rather use file import to get your designs into COMSOL Multiphysics, the product also supports import of the most common 3D CAD file formats: ACIS®, AutoCAD®, IGES, Inventor®, NX®, Parasolid®, PTC Creo Parametric™, PTC Pro/ENGINEER®, SOLIDWORKS®, and STEP. In addition, support for CATIA® V5 is available as a separate add-on. To exchange data with CAD packages, you can export your geometry to the ACIS®, IGES, Parasolid®, and STEP file formats.

Finally, the product provides a dedicated geometric kernel, the CAD kernel, and a wide range of tools for you to prepare an imported 3D design for meshing and analysis. You can interactively search for and remove geometric features, for example, fillets, holes, slivers, small faces, and short edges. You can also modify objects by detaching a portion to form an additional computational domain, or by creating a fluid domain for computation, in case the CAD design only includes the solid parts.
