Abstract

The Modified Local Green's Function Method, MLGFM, has been proposed as an alternative for extending the applicability of the Boundary Element Method to problems which do not have a known fundamental solution. Up to now, most of the published results are based on a global version where only one Green's Cell is used. In this paper, some results for nonlinear potential problems ob- tained by using several Green's Cells are reported and compared against Mixed Finite Element solutions. This comparison illustrates the beneficial effects that the boundary elements bring in the formulation: improved accuracy and fewer iterations in nonlinear problems. Introduction Although the Boundary Element Method, BEM, has long been recognized as an established numerical method with many advantages over other
