Time-periodic Eddy Current Analysis using Model Order Reduction and Time-periodic Explicit Error Correction Method

Abstract

This paper introduces a fast time-periodic eddy current analysis using model order reduction (MOR) and time-periodic explicit error correction (TP-EEC) method. In this method, the size of the original system is reduced by MOR and simultaneously, the convergence to steady states is accelerated by TP-EEC. It is shown that the speedup ratio of the present method compared with the conventional FEM is more than 30 for a nonlinear test problem.
