LiveLink™ for AutoCAD® Updates
For users of LiveLink™ for AutoCAD®, COMSOL Multiphysics® software version 5.4 brings support for synchronizing read-only parameters and object selections generated for material selections. See the LiveLink™ for AutoCAD® updates in more detail below.
Support for Synchronizing Read-Only Parameters
Dimensional parameters that are controlled by an equation in the CAD model can now be transferred during synchronization. These parameters are treated as read-only parameters and are available for use in a COMSOL Multiphysics® model. The values of these parameters cannot be changed inside the model, but they are updated with each synchronization based on the changes in the CAD software.
The d2 parameter is controlled by an equation in this AutoCAD® part file.
After synchronization, the d2 parameter appears in the Read-only parameters table and the associated global parameter, LL_d2, can be used in the simulation setup.
Object Selections Generated for Material Selections
Material selections, which are generated from the material assignments in the CAD model, are now available as general object selections. These selections are available in the lists of input objects for the geometry feature nodes, below the LiveLink™ node in a geometry sequence.
After synchronization, the Copper.surface material selection appears in the Object Selections section.
The Copper.surface material selection can be accessed as input to the Convert to Solid 1 operation to form a solid of all surface objects that have been assigned the Copper material in the AutoCAD® file.
Updated Support for New CAD File Format Versions
The CAD file import and export functionality has been extended to support new versions for the following file formats:
