摘要
在改进节点连接法的基础上，提出了一种平面任意区域的有限元网格全自动剖分方法．既能快速生成四边形单元网格，也能生成三角形单元网格；而且可以很好地控制单元的质量，特别是边界单元的质量；同时可以灵活地进行局部网格加密．
A new method for automatic generation of finite element meshes on arbitrary 2D domain is proposed here by means of improving the nodeconnection method. The method can generate quadrilateralelement meshes as well as triangularelement meshes effectively. The quality of meshes, particularly of elements on boundaries, can be well controlled, and the local meshes can be refined easily.
