A Practical Technique for Generating Hexahedral Meshes

摘要：

　　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.
