Abstract
The nonconformal domain decomposition method (DDM) of the hybrid finite element-boundary element(BEM) with FETI (finite element tearing and interconnecting) like algrithm and multilevel fast multipole algorithm (MLFMA) are presented for computing large electromagnetic scattering problems in this paper. Due to the Robin-type transmission conditions, it is possible to employ nonconformal interface discretizations of the targets. We speed up the solution process by reducing the unkowns by adopting the thought of FETI, leading to sevaral dense FEM inverse matrices. H-Matrices is introduced into this method to reduce memory consumption, when faced with plenty of sub-domains. Furthermore, MLFMA is applied to improve the efficiency of computing technique. Accuracy and efficiency of the proposed method are demonstrated through several numerical experiments.
