| 摘 要： | 有限元的计算结果常需要用等值线表示出来。Surfer是一应用得十分广泛地作等值线的软件，但它仍有不足，如有的等值线所代表的值无法判断等。基于有限元网格和线性插值的方法及其他一些处理技巧，可有效地克服Surfer等软件的缺点，通过VBA语言编程可直接将等值线画在常用的制图软件AutoCAD界面里。所编的程序在平面有限元计算结果的等值线绘制中运用效果良好。

| Abstract: | The result of planar Finite .Element Method (FEM) is commonly expressed by isolines, and Surfer is a software widely used to draw isolines, yet Surfer has many shortcomings, for example, some isoline values can’t be judged. Based on FEM mesh and linear interpolation and other artifices, a VBA program is compiled to overcome the shortcomings, and the isoline can be directly formed in the interface of AutoCAD, that is a widely used cartographic software. The VBA program can be applied to draw isolines in the planar FEM postprocessing. |
