Unstructured mesh is often used for a flow field with complicated shaped boundaries . In particular, a polygonal mesh is more flexible and efficient for mesh generation. Thus, in this paper, a new solution adaptive mesh method combined with a polygonal mesh is proposed. In this method, meshes based on pressure distribution are generated and divided like a super-polygonal mesh. An algorithm with generated and divided meshes is discussed and confirmed in this paper. The method is applied to supersonic flow with shock wave to show a efficiency of computation.
