表面電荷法による電界解析の計算精度(情報処理工学科創設20周年特集号) Computational Accuracy of Electric Field Analysis by Surface Charge Method(Special Edition for the 10th Anniversary of Department of Information Processing Engineering) 坪井, 始 42883 浅原, 知行 42884 小林, 富士男 42885 美咲, 隆吉 42886 電界解析 表面電荷法 境界要素法 計算精度 数値解析 electric field analysis surface charge method boundary element method computational accuracy numerical analysis P(論文) Electric field analysis is performed by using various types of boundary element methods. In this paper, the computational accuracy of surface charge method, which is an indirect method of boundary method, is investigated. The computational accuracy of electric field is determined by the following three kinds of accuracy: the approximation accuracy of boundary surfaces, the approximation accuracy of unknown variables on boundary elements and the integration accuracy of coefficient matrix of simultaneous equations. Here, it is described how the accuracy of electric field calculated by the surface charge method is determined by the three kinds of accuracy. departmental bulletin paper 1996-11 application/pdf 福山大学工学部紀要 1 20 45 51 AN00217655 https://fukuyama-u.repo.nii.ac.jp/record/7992/files/KJ00005781698.pdf https://fukuyama-u.repo.nii.ac.jp/records/7992 jpn
