Abstract

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