A novel mapping technique for open boundary finite element solutions to Poisson's equation

Abstract

The accurate representation of the effects of the exterior region in an unbounded field problem solved by a finite-element procedure is considered. Most procedures require additions to the basic finite-element method. An approach is presented that can yield good results without any code modification and can be used directly with many existing finite-element systems. The method is outlined briefly, its implementations in current CAD systems are described, and illustrations of its use are provided.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
