COMSOL Multiphysics® 6.0 Release Highlights

CAD Import Module Updates

For users of the the CAD Import Module, COMSOL Multiphysics® version 6.0 brings a new Projection operation, improvements to the Detect Interferences tool, and updated CAD file import to support the most recent CAD file versions. Read more about these updates below.

Projection Feature

The new Projection feature, found under the Geometry tab in 2D or the Work Plane tab for work planes in 3D, can be used to project 3D objects and entities, such as faces, edges, and vertices, to work planes and 2D geometries. You can leverage the curve object that results from the projection in further geometry operations, for example, as a construction object that helps with creating other geometry objects, or to convert it into a solid object for setting up a simulation.

The Projection 1 feature, highlighted in the geometry sequence above, projects the highlighted objects onto the work plane, so that they can be used when creating the sketch for the cooling channels in this geometry of a permanent magnet motor.

Improved Visualization for Detect Interferences Tool

The Detect Interferences tool has been improved to better present and visualize the interferences between geometry objects. You can now use the Group by object check box to sort the detected interferences by object. Previously, the list was sorted by the type of interference. As you select an interference from the list, the new default is to visualize only the objects that take part in the interference in the Graphics window; the other objects are hidden automatically. Other options for visualization are also available, for example, to show only the interfering faces.


The Detect Interferences tool is used here to detect and visualize the intersections and touches between the imported geometry objects of a high-voltage circuit breaker chamber.

Updated CAD File Import and Export

The CAD file import and export functionality has been extended to support the most recent versions of the supported file formats. To see a current list of supported CAD file formats, please refer to the Read from File, CAD and Write to File sections on the CAD specification chart.
