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。
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.
