Title:

Optimal Finite Difference Grids for Targeted Approximations

Abstract:

Most numerical methods for PDEs are intended to give equally good results at all points on the domain. However, in geophysical simulations, for example, one really only cares about the accuracy of the solution at prespecified receiver locations. Here we describe an optimal grid approach which is based on rational approximation. We show how it can be used for a variety of physical problems.
