摘要
本文采用十节点曲边四面体转换为六面体网格，并采用非线性约束优化算法取代Ｌａｐｌａｃｉａｎ光滑处理算法有效地提高六面体单元的质量，实现了对任意实体的六面体网格自动划分。
This paper uses the method that transforms each ten noded curved edge tetrahedral
element into four hexahedral elements and constrained mesh optimization techniques are then
employed to improve the quality of hexahedral mesh. Finally, two examples are showed.
