| 摘 要： | Q-Morph算法在用Delaunay方法形成三角网格的基础上，利用已有的网格拓扑关系，提出一种新的四边形生成算法。采用边界推进法来生成四边形网格。该算法生成的网格具有边界敏感性和方位不敏感性，并且能极大地减少网格中不规则点，很大程度上提高了网格质量。

| Abstract: | The Q Morph algorithm proposed was based on triangular mesh generated by Delaunay. Quadrilateral mesh was generated by using advancing front method and the topologies of existing triangular mesh. This algorithm has many desirable characteristics such as boundary sensitive, orientation insensitive, and few irregular nodes, and with a high quality in the resulting mesh. |
