For clusters not in the far field, the traditional BEM has to be applied. That is MLFMM introduces different levels of clustering (clusters made out of smaller clusters) to additionally enhance computation speed.〔(【引用サイトリンク】 title=(Electrically) Large Applications & Integral Equation solver )〕〔(【引用サイトリンク】 title=Multilevel Fast Multipole Method (MLFMM) )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Multilevel fast multipole method」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
