BEM-FEM formulation based on magnetic vector and scalar potentials for eddy current problems

The hybrid boundary element - finite element method (BEM-FEM) has been developed for several decades and has shown many advantages since air media has not to be meshed. In this paper, a new BEM-FEM formulation is presented. It is based on the modified magnetic vector potential A* as unknown in active regions and on the reduced magnetic scalar potential φ as unknown in the air media. The formulation and its numerical validation is proposed in this paper.
