一种改进的二维有限元网格逐次细分法

An Improvement on the Gradual Subdivision of 2D Finite Element Mesh

通过引入相关系数，解决了任意区域三角单元网格的逐次剖分过程中，单元细分后单元编号不连续的情况。采用相关系数法，可方便地对具有多种媒质区域的网格进行加密剖分。

In order to solve the uncontinuity of element numbering after the gradual subdivision of the triangular meshes, the correlation coefficient are introduced in this paper. It is easy to refine a multimedia-domain by using this method.
