However, the . will be shown to be highly suitable for handling layout (topology) optimization problems with a very large number of potential members.

CAD-Integrated Structural Topology and Design Optimization,dmissible structural domain, assuming the loading and boundary conditions to be given. In the general case, this problem consists in determining both the optimal topology and the optimal design of the structure. Here the label “optimal design” covers the optimal shape or sizing of the design.
