摘要
用边界元求解平面拉氏边值问题必须计算两个系数积分矩阵。本文采用一种解析方法推导了使用常单元时系数积分元素的一种简洁表达式,从而避免了数值积分,并通过编程用算例进行了验证。
For the boundary element solution of the two dimensional Laplace equation, the calculation of two coefficient integral matrices is always needed. A simple analytical approach 10 evaluate these coefficient integrals using the constant element is presented in this paper. Two problems are solved by the computer program developed by the authors to illustrate the applicability of the presented formulation.
