摘要：
The overlapping grid or Chimera method for representation of complex geometries within the context of finite difference methods has been used effectively for a variety of problems, particularly in the area hydrodynamic simulation. In this paper, we introduce a second-order unsplit upwind method of Godunov type for curvilinear coordinates and apply it to gas dynamics simulations involving complex geometries by using overlapping grids.
