摘要
本文旨在综述我们小组近二十年来在边界元方法这一领域的一些研究成果,在简要介绍边界元方法的基本思想后,主要介绍了一类非线性界面问题的有限元-边界元耦合方法、求解电磁散射问题的有限元-边界元耦合方法和超奇异积分的一类计算方法.
In this paper we try to recall some main progresses of our group on the boundary element methods in the last 20 years.We first outline the basic ideas of the boundary element methods.Then we simply introduce coupling methods between finite element and boundary element for a certain nonlinear interface problem in unbounded domains,coupling methods between finite element and boundary element for electromagnetic scattering problems and some computational methods for hypersingular integrals.
