满足特征约束任意多连通域的有限元最优三角剖分

针对电机、真空灭弧室的电磁场有限元分析，基于推进波前法提出了一种对带有特征约束的任意多连通域的有限元自动剖分方法———ＭＣＲ 剖分方法．该方法不必添加任何辅助手段，自动满足拓扑相容．对多连通域的包含关系，采用两个一维数组存放，节省了存储空间，便于查询．将特征约束作为“退化”区域对待，使剖分带有特征约束的任意多连通域统一到对子区域的处理上．最后，通过对两个实例的剖分，验证了方法的正确性、简便性和通用性

Novel Fully Automatic Finite Element Mesh Generation for Arbitrary Multiply Connected Regions with Characteristic Constraints

A novel fully automatic finite element mesh generation scheme is developed for arbitrary multiply connected regions as applied to electromagnetic field analysis. It is based on the advancing front method. The compability of the finite elements and the region boundary is satisfied automatically without any aided lines. The characteristic constraints such as lines, fixed nodes and subregions are discussed. Finally, two examples are provided to illustrate how the mesh generation works.
