| 摘 要： | 提出一种在节理网络图上全自动生成有限元网格的方法，并用程序将其实现。该方法首先将具有节理网络的计算域，依据一定算法转化成单连通域，然后在单连通域内按ＡＦＭ法生成三角形单元，在节理上生成节理单元。所有的三角形单元和节理单元构成整个区域的有限元网格。

| Abstract: | A method to automatically generate a FEM mesh on a joint network is proposed and implemented through programming. The whole domain including joint network is first transferred, according to a method, into simplyconnected domains. Then triangle elements are generated by the advancing front method. Joint elements are created on joints. All the triangle elements and joint elements form a mesh for the whole domain. Examples indicate that the proposed method and program are practical. |
