An Iterative Domain Decomposition Method of Magnetostatic Problems Based on a Mixed Formulation

An iterative domain decomposition method is introduced into magneto static problems, which is formulated by a mixed method with the Lagrange multiplier. By introducing the mixed formulation, a two-sub domain problem is equivalent to the conventional one-domain problem, and yields an interative domain decomposition method of magneto static problems. Moreover, the method has some relations with another one, where the magnetic vector potential is regarded as only one unknown function.
