Treating Imported ECAD Files
Depending on the file format, the import functionality provides options for configuring the cells or nets that should be used for geometry construction. You can also exclude layers, edit layer thicknesses and elevations, decide how bond wires should be represented in the final geometry, and even fine-tune the parameters for arc recognition. For a faster set-up of the import process, it is possible to load the layer configuration information from a text file. To further shorten the time spent on setting up simulations, you can configure the import to automatically create selections for each layer. These selections are then available when you are assigning physics settings to domains and boundaries.
The 3D geometry objects constructed from the ECAD layouts can be further modified using available features in COMSOL Multiphysics. When combined with the CAD Import Module, Design Module, or one of the LiveLink™ products, the 3D geometry can be exported to the IGES, STEP, ACIS® or Parasolid® file formats for use in other software.

Importing and Meshing a PCB Geometry from an ODB++ Archive
This tutorial model shows how to import data from an ODB++® archive to generate a geometry of a printed circuit board (PCB). Follow the instructions to learn how to remove small details from the geometry, create a mesh, and use automatically generated selections to define physics and mesh settings. _The ODB++® file is provided through the ...
