COMSOL Multiphysics® 5.6 Release Highlights

LiveLink™ for Inventor® Updates

For users of LiveLink™ for Inventor®, COMSOL Multiphysics® version 5.6 brings two new defeaturing and repair tools, as well as a new tutorial model. Read more about these updates below.

Detect Interferences

The Detect Interferences tool, added to the Defeaturing and Repair menu, can detect interference between objects. This tool supports solid and surface objects as input and detects intersections, touches, gaps, and containments. You can see this feature demonstrated in the Creating a Fluid Domain Inside a Solid Structure tutorial model.

Several intersections, touches, and gaps are detected in this imported CAD assembly, including information about the objects and faces involved in the interferences. Gaps are listed together with the gap distance, and the Zoom to Selection button makes it easy to find the location of the interfering faces on the geometry.

Check Feature

The new Check feature, added to the Defeaturing and Repair menu, can be used to detect faults in CAD objects. Add a Check node to a geometry sequence, such as after a Delete Faces operation, to confirm that no problems remain after replacing a faulty face.

No faults remain in this geometry after replacing the faulty face using the Delete Faces operation.

New Tutorial Model: Geometric Parameter Optimization of a Bracket

The Bracket Optimization tutorial model minimizes the mass of a bracket that is synchronized from Inventor® via the LiveLink™ interface. There are limits both for the lowest natural frequency and the maximum stress in a static load case. The size and position of a number of geometrical features are changed to optimize the mass, while several geometrical constraints are enforced to maintain the design intent.
