Abstract

A novel hybrid finite element method(FEM)-boundary element method(BEM) with full scalar potential in ferromagnetic region and reduced scalar in free space for open boundary magnetostatic problems is proposed. Through the continuity condition on the interface, the term of coupling between the double scalar potentials is deduced. The Galerkin weighted residual method is used to derive the coupling formulation of hybrid FEM-BEM. Several numerical examples to magnetostatic problems are presented. The calculated results are well agreed with the analytic results.
