This paper deals with a hex-dominant mesh generation using an advancing front methods for three-dimensional geometries. Hexahedral and prismatic meshes are generated inwardly by offsetting from initial boundary mesh. When the meshes intersect with each other after offsetting, overlapped meshes are improved by node relocation method. In order to generate conforming mesh, pyramid elements are inserted between hexahedral and tetrahedral elements. Sample meshes for several geometries are presented and analized to demonstrate the effectiveness of the proposed algorithm.
