Large-Scale Magnetostatic Domain Decomposition Analysis Based on the MINRES Method

Year: 2013

Type: article

Abstract: This paper describes a large-scale 3D magnetostatic analysis using the Domain Decomposition Method (DDM). To improve the convergence of an interface problem of DDM, DDM based on the Conjugate Residual (CR) method or the MINimal RESidual (MINRES) method is proposed. The CR or MINRES method improves convergence rate and shows stable convergence behavior in solving the interface problem, compared with the Conjugate Gradient (CG) method, and reduces the computation time for a large-scale problem with 100 million degrees of freedom.
