This paper presents a modified version of the hybrid FEM-DBCI (Finite Element Method-Dirichlet Boundary Condition Iteration)method to solve static and quasi-static electromagnetic field problems in open boundary domains. The modification consists of overlappingthe fictitious truncation boundary with the integration one, as in the FEM-BEM (Boundary Element Method) method. The globalalgebraic system obtained is solved iteratively by means of the GMRES (Generalized Minimal Residual) solver, applied virtually to areduced system in which the unknowns are those relative to the potential on the truncation boundary only.

Abstract
This paper presents a modified version of the hybrid FEM-DBCI (Finite Element Method-Dirichlet Boundary Condition Iteration)method to solve static and quasi-static electromagnetic field problems in open boundary domains. The modification consists of overlappingthe fictitious truncation boundary with the integration one, as in the FEM-BEM (Boundary Element Method) method. The globalalgebraic system obtained is solved iteratively by means of the GMRES (Generalized Minimal Residual) solver, applied virtually to areduced system in which the unknowns are those relative to the potential on the truncation boundary only.
