| 摘 要： | 介绍常用的电磁场分析方法——解析法、有限差分法、有限元法.以静态电磁场边值问题为例,分别用自己编写的MATLAB有限差分程序及大型有限元分析软件ANSYS求出了数值解,并与解析法得到的精确解进行比较,得出了用数值法求解电磁场问题基本满足工程需要的结论.采用数值计算时,对如何减小计算机内存,取消冗余数据,也做了进一步的讨论.

| Abstract: | A few methods for calculating electromagnetic field are introduced-analytical method, finite difference method, finite element method. A static electromagnetic problem is taken as an example. Numerical solution are achieved by MATLAB finite difference program which programed by the author and ANSYS plat- form. By comparing numerical solution and anlytical solution, the conclusion that the numerical solution is satisfied for engineering are achieved. How to reduce the computer memory and redundant data are discussed as well. |
