Mortar Method Using Bi-Orthogonal Nodal Functions Applied to ${\rm A}\hbox {-}\varphi$ Formulation

For a magnetodynamic problem decomposed into subdomains, the Mortar method can be associated with potential formulations to connect nonconforming meshes. In this paper, we propose to use the bi-orthogonal nodal shape functions with the Mortar method in the case of A-φ formulation. Academic examples will be studied to shown the efficiency of the proposed model.
