快速大规模边界元算法

Fast large-scale boundary element algorithms

Steffen Börm

摘要:

边界元方法将区域中的偏微分方程转化为区域边界上的积分方程。它们对于求解无界域上的问题特别有吸引力,但是处理对应于积分算子的稠密矩阵需要有效的算法。本文介绍了两种方法,使我们能够解决边界元方程的表面网格组成的数百万个三角形,同时保持最佳的收敛速度的Galerkin离散。

英文摘要:

Boundary element methods (BEM) reduce a partial differential equation in a domain to an integral equation on the domain's boundary. They are particularly attractive for solving problems on unbounded domains, but handling the dense matrices corresponding to the integral operators requires efficient algorithms. This article describes two approaches that allow us to solve boundary element equations on surface meshes consisting of several millions of triangles while preserving the optimal convergence rates of the Galerkin discretization.
