topology optimization

Topology optimization (TO) technique has been developoed to find the best possible layout (material distribution) of structures. Figure shows a result of 3D topology optimization using the constrained adaptive topology optimization (CATO) algorithm. From the initial hexahedron shape of design domain with natural and essential boundary conditions, the optimum topology is produced.
