摘要
提出了应用组合网格法解决电磁问题的思想。论述了该方法的基本原理和计算步骤,将计算结果与单套网格的计算结果比较,总结了该方法应用过程中应注意的问题。指出了当粗细网格材料不同时应在细网格区域外加一层粗网格区域的材料,从而提高解的精度。将该方法应用于一个运动电磁问题,证明了它的有效性和准确性。
In this paper, a novel method--combined grid method is used in electromagnetic problem. The basic theory of the method is demonstrated and the calculation step is presented. Through the comparison of the results of the combined grid method and the one grid method, problems that exist in the process of the modeling are shown. Technique to tackle the problem is figured out. The method is used in an electromagnetic problem which involved movement. Numerical results illustrate the efficiency and the accuracy of the proposed method.
