Based on the stress map, the CATIA R21 optimization algorithm identified material regions that carried minimal load.

However, a limitation noted was the computation time for high-density meshes. For highly complex assemblies, the native solver in R21 is slower compared to dedicated standalone FEA software.

It operates within the V5 architecture, focusing on a parametric, feature-based approach to modeling, which allows engineers to create, modify, and manage complex 3D models efficiently. 2. Key Modules and Capabilities in CATIA R21
