Keywords: cfd, grid generation, unstructured grid, aerodynamic analysis

A new hybrid unstructured CFD grid system was developed. This new hybrid grid system is applicable both viscous and invscid flow analysis for complex geometry. Most volume grid cells consist of hexahedra and prism cells. Small portion of pyramid and tetrahedral cells are used as a link between hexahedral cells and prism cells.
