Abstract

We propose a mapping operator construction technique for error correction methods applied to a series of linear systems. The mapping operator is constructed based on information obtained in the previous solution step. The additional memory requirement for the construction is limited. Our numerical experiments based on an electromagnetic field analysis confirmed that the correction method with the proposed mapping operator improves the convergence of the iterative solver.
