Projecting discrete quantities from one mesh to another one is a critical operation which is usually required in multiphysical problems. The efficiency of a Galerkin projection method is studied for magnetothermal and magnetoelasticity couplings. As examples of application, two electromagnetic (EM) devices are studied: a three-phase busbar system as a magnetothermal problem and an electromagnet as a magnetomechanical problem.
