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.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.137 No.3 （2017） 特集：電力・電気機器関連の電磁界数値解析本誌掲載ページ: 202-207 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejpes/137/3/137_202/_article/-char/ja/ Show more
