Finite Element Analysis of High Frequency Electromagnetic Fields Using a Domain Decomposition Method Based on the COCR Method

Abstract

This paper describes an analysis of high frequency electromagnetic fields using the finite element method of Maxwell equations including the displacement current. To solve a large-scale complex symmetric problem on a parallel computer efficiently, a domain decomposition method based on a COCR method is proposed. The COCR method improved convergence behavior in solving an interface system as compared to the COCG method, and then significantly reduced the computation time for the large-scale problems.
