摘要
确立平面位势的边界元直接法中边界积分的解析计算框架系统 ,从而避免了传统的高斯近似求积分 .数值算例表明它具有较高的精度和效率 .特别是在边界量和边界附近区域内点物理量的计算可获得较高的精度 .
An analytical scheme, which avoids using the standard Gaussian approximate quadrature to treat the boundary integrals in direct boundary element method of two-dimensional potential problems, is established. With some numerical results, it is shown that the better precision and high computational efficiency, especially in the band of the domain near boundary, can been derived from present scheme.
