LiveLink™ for Solid Edge® Updates

For users of LiveLink™ for Solid Edge®, COMSOL Multiphysics® version 5.6 brings two new defeaturing and repair tools, as well as a new and updated 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.

Demonstrating the Detect Interferences tool 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 Solid Edge® 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.

Updated Tutorial Model: Electrical Heating in a Busbar Assembly

This updated tutorial model analyzes a larger busbar assembly designed to conduct direct currents, from a current source to the anode, in an electrolysis process. Selections defined in the CAD assembly files are used to assign materials and boundary settings in the simulation. A parametric sweep over two parameters in the Solid Edge® assembly has been included to study the influence of the geometry on the physics phenomena, and the results of the sweep are visualized through a Table Surface plot. This can help in selecting geometric parameter combinations that keep the maximum temperature in the copper components below the desired maximum value.
