Known issues

• After the FEA for the original model, you have to close the CGX window to proceed to BESO.
• Finite elements are generated by SDFX package. There is a known issue: Megidd/Feather#2

Why this plugin?

An in-depth description of BESO and its capabilities are available on the wiki.

Commands

This plugin offers a BESOTopologyOptimization command to optimize usage process. Making sure your 3D model has maximum strength and minimum weight.

BESOTopologyOptimization command

This command helps you optimize the toplogy of 3D model. You can keep the model strength while decreasing its weight. The finite element analysis - FEA - along with topology optimization are the technologies under the hood. FEA will be done according to user-selected loads and restraints. An optimized 3D model will be generated. Some elements of the original 3D model are removed without affecting the required strength.
