对四边形网格自动生成方法进行了研究。将目前网格划分效果较好的铺路法进行了改进 ,重新设计了网格生成的总体算法 ,单元由边界向区域内部不再逐层生成 ,而是逐段或逐个生成 ,直至网格布满整个区域。本算法还解决了有关的关键技术 ,其中包括网格交叉处理 ,边界的光滑处理 ,网格的整合和光滑等。最后给出了网格划分实例 ,验证了算法的可靠性和稳定性。

The automatic generation algorithm of quadrilateral elements for finite element analysis is studied in this paper. The paving algorithm is improved and its control sequence is redesigned. The elements are generated row by row or one by one, not layer by layer,from the boundary to interior until the entire zone is filled with elements. Several key techniques are also solved, including mesh intersecting, boundary smoothing, mesh smoothing and cleanup etc. Finally,the several meshing examples are given.The validity and reliability of the algorithm are proved.
