Abstract

This work presents a multi-domain decomposition integral equation method for the numerical solution of domain dominant problems, for which it is known that the standard boundary element method (BEM) is at a disadvantage in comparison with classical domain schemes, such as finite difference (FDM) and finite element (FEM) methods. As in the recently developed Green element method (GEM), in the present approach the original domain is divided into several sub-domains. In each of them the corresponding Green's integral representational formula is applied, and on the interfaces of the adjacent sub- regions the full matching conditions are imposed. In contrast with the GEM, where in each sub-region the domain integrals are computed by the use of cell integration, here those integrals are transformed int
