FEM/DBCI (Dirichlet Boundary Condition Iteration) Is a hybrid method which
has been successfully applied to the finite element solution of static and
quasistatic unbounded field problems. It is based on the iterative improvem
ent of a Dirichlet condition on a fictitious boundary enclosing all the con
ductors, making use of the free-space Green's function. In this paper it is
shown that for two-dimensional skin effect problems a more robust solving
strategy can be pursued by means of GMRES, obtaining a reduction in both CP
U and storage requirements.
