LiveLink™ for Inventor® Updates

For users of LiveLink™ for Inventor®, COMSOL Multiphysics® software version 5.3a brings updated tutorial models and extends support to new versions of certain CAD file formats. Read more about the LiveLink™ for Inventor® updates below.

Updated Tutorial Model: Electrical Heating in a Busbar

This tutorial model now transfers material selections assigned to components in the Inventor® assembly over to the COMSOL Multiphysics® software automatically. After synchronization, the selections are used to define materials on the geometry in the COMSOL Multiphysics® model. User-defined selections in the Inventor® assembly are also synchronized and used for assigning boundary conditions in the analysis. A parametric sweep over two-dimensional parameters in the Inventor® assembly has been included to study the influence of the geometry on the physics phenomena, shown with a Table Surface plot in the results.

The selections defined in the COMSOL Selections window inside the Inventor® software are available after synchronization to define the boundary settings in the COMSOL Multiphysics® model.

Updated Tutorial Model: Pacemaker Electrode

This tutorial now uses selections defined on the geometry in the Inventor® part file as an input to the boundary conditions when setting up the analysis inside the COMSOL Multiphysics® software. Defining selections in the Inventor® part file results in a faster and more robust workflow when performing geometric parameter sweeps and optimization of geometric parameters.

Updated Support for New CAD File Format Versions
