Abstract
In shape optimization, an optimal shape is generated by moving some nodes of an initial mesh. But there are many cases that meshes can not follow the movement of nodes. In this paper, the shape optimization technique using mesh superposition method is proposed. In the present technique, the shape of design domain is represented by local mesh to allow flexible shape control. The shape of the local mesh is controlled by basis vector method. Several examples which can not optimize in the conventional optimization technique are shown to demonstrate the effectivity of the present method.
