摘要
本文提出用边界元法计算介质分区均匀情况下的静电场第四类非混合边值问题,推导出用边界元法计算第四类非混合边值问题的边界元方程组。理论分析和实例计算结果表明:边界无法是计算第四类非混合边值问题的一种有效方法,不仅具有较高的计算精度,而且可以很方便地应用于静电场工程问题的设计与计算。
A modified boundary element method (BEM) is presented for computation of the fourth non--mixed boundary--value problems of electrostatic field. The BEM equation is derived, and the equation of constraint is presented. By theoretical analyzing and calculating engineering examples, it is proven that the BEM is a more effective approach to computation of the fourth non--mixed boundary--value problems of electrostatic field, it may obtain better calculating results and is applicable to calculating electrostatic field engineering problems of the fourth non--mixed boundary--value problems.
