Optimizable Element Types

In general, SIMULIA Tosca Structure allows all element types listed in the table below in the optimization area. However, there are exceptions: For supported element types in shape sensitivity optimizations see Supported elements attached to shape sensitivity design nodes. Details concerning specific element definitions for the several solvers are listed in Solver Specific Features. Some design responses are not allowed for all element types. This can be found in the corresponding paragraphs of Terms for Optimization.
