The LiveLink™ bidirectional interface enables synchronization of geometry from AutoCAD® to COMSOL Multiphysics®. The synchronized geometry in the COMSOL model stays associative with the geometry in AutoCAD®, which means that settings you have applied to the geometry, for example physics interface or mesh settings, are retained after subsequent synchronizations. In addition, you gain control of the AutoCAD® geometry dimensions from within the COMSOL model. This functionality allows for automatic parametric sweeps, or automatic shape optimization available with the Optimization Module.
