Numerical Boundary Conditions for Wave Propagation Problems

这项研究涉及研究以下问题： 波传播问题的开边界条件， 用数值方法实现这些边界条件。 的主题 包括对瑞利效应的分析 辐射边界条件的波以前开发的 弹性体波的研究者， 分析了水波的辐射条件， 关于导数若干理论问题的探讨 在开放边界上使用的边界条件。 第一 有两个问题需要大量的数值计算。

This research is concerned with studying questions regarding open boundary conditions for wave propagation problems and with implementing numerically these boundary conditions. The topics on investigation include an analysis of the effect on Rayleigh waves of radiation boundary conditions previously developed by the investigator for elastic body waves, the development and analysis of radiation conditions for water waves, and the investigation of some theoretical questions involving derivative boundary conditions that rae used at open boundaries. The first two problems will require extensive numerical computation.
