Weighted-residual finite element mesh coupling

摘要

A weighted-residual method is presented to address the problem of coupling two separate meshes sharing a common boundary. It is shown that the imposition of a potential continuity condition together with a suitable penalty constant can be used to achieve the coupling. The further requirement of continuity of the normal derivative results in a quicker convergence. A magnetostatics test problem in two dimensions is used to verify the scheme. The method can be used in movement simulation of magnetic devices.
