| 摘 要： | 针对六面体网格自动划分的难度远高于四面体网格的问题，用投影法对简单形状的初始网格进行投影变换得到每个块体的实际网格，用节点合并算法和再分割技术实现不同块体之间的不同密度网格的过渡，从而生成复杂三维几何形体的全六面体网格.算例表明：该方法生成的网格质量很好，易于实施，适用性广.

| Abstract: | As to the issue that the automatic hexahedral meshing is far more difficult than the automatic tetrahedral meshing, the projection method is used to transform the initial mesh of simple shapes into the actual mesh of each block, the mesh transition among blocks with different mesh density is implemented by node merging algorithm and resegmentation technique. The numerical examples show that the mesh quality generated by the method is good and the method is easy to bring into effect with wide applicability. |
