The discrete arti®cial boundary condition on a polygonal arti®cial boundary for the exterior problem of Poisson equation by using the direct method of lines

Abstract

The numerical simulation for the exterior problem of Poisson equation is considered. We introduced a polygonal arti®cial boundary Ce and designed a discrete arti®cial boundary condition on it by using the direct method of lines. Then the original problem is reduced to a boundary value problem de®ned in a bounded computational domain with a polygonal… (More)
