Abstract
This paper presents a unified FETI/FETI-DP framework for a general domain decomposition solution of electromagnetic problems. This method fully takes advantage of the global corner system to construct an effective coarse grid correction for the global interface problem when dealing with the mesh-conformal part. For the mesh-nonconformal part, it employs the second-order transmission condition to improve the convergence of the global interface problem. The proposed method is validated with wave propagation and antenna radiation examples.
