| 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. |
