Combination of finite and boundary elements for magnetic field analysis

A procedure is proposed which utilizes combined Finite Elements Method and Boundary Elements Method for magnetic field analysis. Given a region constituted by sub-regions, some of which require a dense discretization, the field analysis is carried out by using the Finite Elements Method, and the Boundary Elements Method is used for the other sub-regions which require a large discretization. The procedure is applied for studying the magnetic field due to a coil and the obtained results are compared with the values given by formulas known in the scientific literature[5].
