Abstract :
This paper presents a modified version of the hybrid FEM-DBCI method for the solution of time-harmonic skin effect problems in open boundaries. In this new version of the method the fictitious truncation boundary coincides with the integration one, as in the FEM-BEM method. The global algebraic system obtained is solved iteratively by means of the GMRES solver. Some validation examples are provided.
