摘要
利用边界元方法将调和方程边值问题转化为求解边界积分方程的问题,介绍了这种边界积分方程(Poisson积分方程)的配置算法.主要讨论了所得配置解余项的渐进展开式,并通过它获得了具有O(h3)高精度的外推解.
The harmonic equations and the boundary integral eqaations were solved by using the boundary element methods. And the collocation method for solving this integral equation (Poisson integral equation) was introduced. The asymptotic expansion for the remainder of the collocation solution was discussed,from which the extrapolation solution with high accuracy 0( h3 ) was obtained.
