The hybrid grid is capable of preserving the advantageous features of both the structured and unstructured grids,and eliminates or minimizes their shortcomings [1,2].The generation of hybrid grids is a promising topic in the community of grid generation.In this study,a novel hybrid grid generation approach is investigated for viscous flow computations,where semi-structured prisms and unstructured tetrahedra are configured in the viscous layer and far field of the computational domain,respectively.Given the fact that tetrahedral grid generation can now manage very complicated geometric configurations [3],reliable grid generation for viscous layers is the main unresolved issue of this hybrid grid generation approach [4,5].
