Abstract

A simple mesh/grid free numerical method for Poisson's equation has been developed to solve large scale problems in three-dimensions, In this paper, the Poisson's equation is split into two parts by using the method of par- ticular solutions; the particular solution being approximated by the dual reciprocity method (DRM). In the DRM, we choose compactly supported radial basis functions for the interpolation of the forcing term. To then achieve a true meshless method, we employ the method of fundamental so- lutions (MFS) in order to solve the resulting homogeneouse quation. The approach developed here is especially attractive for
