LiveLink™ for PTC® Pro/ENGINEER® Updates

For users of LiveLink™ for PTC® Pro/ENGINEER®, COMSOL Multiphysics® software version 5.3a brings an updated tutorial model and extends support to new versions of certain CAD file formats. Read more about this LiveLink™ for PTC® Pro/ENGINEER® update below.

Updated Tutorial Model: Electrical Heating in a Busbar

This tutorial now uses selections that were synchronized to the COMSOL Multiphysics® model from materials assigned to the components in the PTC® Pro/ENGINEER® assembly. After synchronization, the selections are used to assign materials on the geometry in the COMSOL Multiphysics® model more easily. A parametric sweep over two-dimensional parameters in the PTC® Pro/ENGINEER® assembly has been included to study the influence of the geometry on the physics phenomena, with a Table Surface plot included in the results to visualize this.

An assembly file is synchronized over to the COMSOL Multiphysics® software, with titanium and copper material selections automatically imported over from the PTC® Pro/ENGINEER® software. The 2D plot can help in selecting geometric parameter combinations that keep the maximum temperature in the copper components below the desired maximum value, 90 degrees Celsius in this case.
