A Practical Technique for Generating Hexahedral Meshes

Abstract:

A practical technique for generating hexahedral meshes automatically is proposed in this paper. The technique is accomplished by secondary subdivision of a tetrahedron. The implementation method from tetrahedron to hexahedron through secondary subdivision is discussed. The method and treatment of boundary condition formula are derived, and the simple and practical load processing method is given. Finally a tetrahedron-based hexahedron automatic meshing program is developed. Engineering examples shows that the calculation accuracy of the method is comparatively high. The proposed method can be applied to any entity.
