二维电法数值模拟中的网格剖分方法

ALGORITHM OF GRIDDING USED IN 2-D RESISTIVITY DIGITAL MODELING

本文提出一种新的有限元及有限差分等方法中的网格剖分及单元电阻率值设置算法。由此算法设计的软件，使用者只需输入地电体的边界顶点坐标及其电阻率值，程序就可自动判断及设置各单元电阻率值，对程序使用者来说极为简单方便。

A new algorithm of gridding and auto-risistivity-setting used in the finite element method (FEM)or finite-diflerence method(FDM)is discussed in this article。The software based on this algorithm is flexible for the user to form the domain grid and set the element resisitivity only by inputting the bound-ary coordinates and resistivity of the electrical inhomogeneity。
