Topology optimization method shows rapidly new development with discretization methods of the partial differential equation such as FEM and BEM. There are homogenization, cellular automata, evolutionary methods in this research field. The target of topology optimization is to have no restriction on the final form of the structure. The proposed self-organization method under the category of evolutionary methods is based on the simple concept that by removing under-stressed materials and simultaneously adding newly surrounding materials to over-stressed materials using the local rule. We show a numerical simulation method of topology optimization by FEM. The effectiveness of the developed simulation program is demonstrated by several examples and discussed fundamental important parameters etc.
