摘要：

In this paper, we present a new methodology for an overlapping domain decomposition by using higher-order MoM and out-of-core solver (HO-OC-DDM) for analyzing large electromagnetic (EM) problems. This paper proposes two main novelties. First, the required number of meshes is decreased with the application of new higher-order basis function in the discretization of integral equation (IE). As a consequence, the number of unknowns for large EM problems can be reduced. Second, a parallel out-of-core solver is presented in this paper, which can accelerate the matrix filling and solving process without loss of accuracy. The out-of-core solver breaks the limitation of computer RAM and can be efficiently implemented in domain decomposition method (DDM).
