摘要
使用计算机进行电磁场数值分析已成为电磁场的工程开发、科研和教学的重要手段。编程实现从电磁场微分方程到有限元求解全过程需要很好的理论基础和编程技巧,难度较高。该文介绍了电磁场数值分析的基本理论并通过两个实例介绍了使用MATLABPDE工具箱实现电磁场偏微分方程的有限元解法。实验结果表明这一方法具有操作简单明了,运算速度快,计算误差可控制等优点。
Numerical analysis by computer is now an important way to development,research and teaching of electromagnetic field.Good theory foundation and programming skill are necessary for programming to solve the electromagnetic partial differential equation by FEM method.This article introduces the basic theory of Electromagnetic Field Numerical Analysis and the FEM method to solve electromagnetic partial differential equation by MATLAB PDE Toolbox.The results show that this method is easy to handle and easy to control the error with faster operation speed.
