An h-formulation for the computation of magnetostatic fields. Implementation by combining a finite element method and a boundary element method

Abstract

A new formulation of magnetostatics is given: it uses the magnetic field h as variable and a penalty technique. For its discretization, a finite element method inside the magnetic materials is combined with a boundary integral method which describes the exterior domain. Numerical tests are presented. The value to be chosen for the penalty parameter and a criterion of validity of the computation are given.
