A subproblem finite element method for solving eddy current problems is developed to correct the inaccuracies near edges and corners arising from thin shell models. Such models replace thin volume regions by surfaces but neglect border effects in the vicinity of their edges and corners. A thin shell solution, performed on a simplified mesh near the thin structures, serves as a source of a correction problem consisting of the actual volume thin regions alone. The meshing effort can be thus concentrated on these thin regions. The general case of multiply connected thin regions is considered.
