摘要

对现有的边界积分方法中对不连续角的容错方法进行了回顾，强调了角相邻面板积分的困难。引入了一个扩展的拉普拉斯角楔来解决这些障碍，基于对角节点和角相邻节点的双三次近似。数值实验证明了该方法具有良好的精度。

Corner problem for the boundary integral method

A review of existing approaches to the accommodation of discontinuous corners in the boundary integral method highlights difficulties with corner-adjacent panel integration. An extended Laplace corner wedge is introduced to resolve these impediments, based on a bi-cubic approximation to the corner and corner-adjacent nodes. Numerical experiments demonstrate the excellent precision of the methodology.
