Abstract

A parallelized multi-solver algorithm based on Robin transmission condition (MS-RTC) is developed on distributed computing systems. To solve large and complex electromagnetic problems using the MS-RTC method, the object with its background is partitioned into multiple non-overlapping subdomains based on their respective material properties, which are modeled by either the finite element method or the method of moments (MoM). Each subdomain problem in the MS-RTC method is solved in parallel to achieve a better efficiency. In particular, for the subdomains modeled by the MoM, the parallelized multilevel fast multipole algorithm is applied to accelerate the computation on many processors. Numerical examples are given to show the parallel efficiency and modeling capability of the proposed algorithm.
