Creating CAD Designs

The Design Module expands the geometric modeling functionality of COMSOL Multiphysics® software by providing additional tools for creating geometries and importing a variety of CAD file formats. The preparation of a geometry is an important part of the simulation process, where the focus is on finding the most suitable way to represent the CAD design for analysis.

This could involve identifying whether certain geometric details are relevant to the analysis or whether a shell approximation can be used instead for the simulation. In other situations, you may need to modify and re-parametrize certain features of an imported CAD design. Or, you may even need to construct a new and simpler parametrized geometry from the ground up, in order to capture the relevant design features for a proper analysis. The Design Module achieves this by manipulating geometries using the Parasolid® geometric kernel.

Import and Export Your Models from and to CAD Software

Import of a number of different file formats – including the Parasolid® software, ACIS® software, STEP, and IGES formats – are supported by the Design Module. Moreover, you can import the native file formats of a number of CAD tools, such as the Autodesk® AutoCAD® software, Autodesk® Inventor® software, NX™ software, PTC® Creo® Parametric™ software, and SOLIDWORKS® software.

The Design Module provides a robust tool to facilitate the integration of both simulation and CAD design within the product development process. When all changes to a geometry have been made, the Design Module can export them in the Parasolid® software or ACIS® software file formats for import into other tools.
