Synchronize CAD Geometries in AutoCAD® and COMSOL Multiphysics®
LiveLink™ for AutoCAD® enables synchronization between a COMSOL® model's geometry and the corresponding AutoCAD® file. LiveLink™ for AutoCAD® ensures that design changes are propagated automatically, eliminating the need to import and export designs each time they are updated. When synchronizing the geometry between the two programs, material and physics definitions as well as boundary conditions remain associated with their respective CAD entities, even when a design has changed. LiveLink™ for AutoCAD® also keeps track of the synchronized file's name and path, as well as the layer state, to prevent synchronizing an incorrect document.
The LiveLink™ for AutoCAD® functionality includes several options for importing geometry into COMSOL Multiphysics® from AutoCAD®. The length unit can be taken from the CAD document (the default option) or from COMSOL®. The object that's imported from AutoCAD® will include solids, surfaces, curves, and points, but the user can choose to exclude any of these if it is not applicable to the simulation.
