这些笔记发展了卷积方程的算法方面及其通过卷积正交的离散化,重点是在波散射问题的边界积分方程公式中出现的卷积方程。作者从多个不同的角度探讨了文商的发展。给出了实现CQ的清晰算法。最后一个例子将整个课程结合在一起,演示了在时间上使用卷积正交对时域边界积分方程进行完全离散化,以及在空间上使用易于编程的Nystrom风味方法。
These notes develop the algorithmic aspects of convolution equations and their discretization by Convolution Quadrature, with an emphasis on the convolution equations that occur in the boundary integral equation formulation of wave scattering problems. The authors explore the development of CQ from a number of different perspectives. Clear algorithms for implementation of CQ are presented. A final example brings together the entire course to demonstrate the full discretization of a time domain boundary integral equation using Convolution Quadrature in time and a simple to program Nystrom flavored method in space.
