There are three distinct categories of structural optimization as follows: (1) Shape optimization, (2) Size optimization, (3) Topology optimization. Each one has a different solution strategy. The third method shows rapidly new development with approximate discretization method of the partial differential equation such as FEM, BEM and FDM. The object of topology optimization is to have no restriction on the final form of the structure. The self-organization method is based on the simple concept that by removing under-stressed materials and simultaneously adding newly surrounding materials to over-stressed materials. The effectiveness of the present simulation method is demonstrated by the numerical examples of the topology optimization problem.
