| 摘 要： | 现有的全自动网格划分算法大部分生成三角形网格。生成四边形网格更困难。为了缓解这个问题，本文研究并实现了三角形网格转化为四边形网格的线性算法。该算法是对已有的Ｏ（Ｎ＾２）算法的改进。

| Abstract: | ost of the fully automatic finite element mesh generation algorithmsexisted generate triangular meshes. It is more difficult to generate quadrilateralelements.In order to alleviate this problem, a linear algorithm for generatingquadrilateral elements from a triangular mesh has been implemented in this paper. It isan improved algorithm of an existed algorithm of O(N') time complexity. |
