Overset Unstructured Grids method is extended to the viscous flow computations of the multiple bodies in contact. In this paper, the overset treatment of hybrid meshes composed of tetrahedral, prismatic, pyramidal elements. is discussed in detail when those elements are embedded or contacted to the wall boundary of another grid. This method is applied to the ONERA M5 wing-body model and computed by the Navier-Stokes code. The computational results show good agreements with those obtained by single grid and experimental data. The boundary layer in the intersection region between two grids is well captured without the collar grid.
