| 摘 要： | 本文应用逆矢径变换,将延展至无限远处的场域变换到一有限空间内,从而使有限元法的求解过程体现于整个无界空间,实现了有限无法在无界的电、磁场问题分析计算中的应用.并且在特定情况下,还可因变换后场域边界形状的变化进一步简化问题的求解.文中还以无界空间中典型电磁场问题为例证.实例表明,由有限元法与逆矢径变换法相组合构成的本方法简单易行,具有实用价值。

| Abstract: | The inverse radius vector transform is applied in this paper to change the boundless space into a bounded domain,so that the finite element method can be used in computing electromagnetic fields with open boundaries.Besides,this method also enables to change the shape of domain boundaries to facilitate problem solving. The method presented in this paper is illustrated by several typical exam- ples.The results obtained check very well with the analytical solutions.This method proves to be effective and simple for solving 2-d and 3-d electromag- netic field problems. |
