【摘要】 在二维电磁场数值分析中,有限元-边界元耦合法将有限元法与边界元法结合,可以同时发挥两种方法的优势.笔者在介绍有限元-边界元耦合法原理与算法的基础上,分别研究子域逼近有限元法、Mortar元法和并行计算与有限元-边界元耦合法结合使用分别为关心区域相对整体区域尺寸较小、求解区域中包含运动导体和大规模高自由度电磁问题的数值计算提供优化途径.更多还原

【Abstract】 Finite element and boundary element coupling method could combine finite element method with boundary element method in 2D electromagnetic field analyses.This paper gave the fundamental of finite element and boundary element coupling method.Sub- region approximation finite element method,mortar element method and parallel computing were introduced respectively for the use of problems with small size research area compared with big size,motion conductor contained in the research area,and numerical analysis for large scale electromagnetic field.更多还原
