摘要: 应用直接边界元素法求解表征寄生电阻电容的混合边界条件拉普拉斯方程,处理角点法向电场间断是一个难点。作者曾提出多重法向导数方法处理2-D角点问题,取得良好效果[2,4]。本文详细介绍多重法向导数方法在3-D情形的推广,并给出数值例子。

Abstract: The parasitic resistance and capacitance can be characterized by the Laplace equation with combined boundary conditions and it can be solved by using the direct Boundary Element Method(BEM).But, it is difficult to treat the discontinuity of normal electric field at corners. The first author of this paper has ever applied a ocncept of multiple normal derivatives at a corner to hadle 2-D problems, and it works efficiently [2,4]. This paper extends the concept to 3-D simulation. Some numerical examples are presented.

Key words: Parasitic resistance & capacitance, Direct boundary element method, Linear element, Multiple normal derivatives
