THE USE OF DIRECT METHODS FOR THE SOLUTION OF THE DISCRETE POISSON EQUATION ON NON-RECTANGULAR REGIONS
Abstract
Some direct and iterative schemes are presented for solving a standard finite-difference scheme for Poisson's equation on a two-dimensional bounded region R with Dirichlet conditions specified on the boundary of R. These procedures make use of special-purpose direct methods for solving rectangular Poisson problems. The region is imbedded in a rectangle and a uniform mesh is superimposed on it. The usual five-point Poisson difference operator is applied over the whole rectangle, yielding a block-tridiagonal system of equations.
