— Study of elastic deformation due to magnetic force —

st floor, office no. 105 Context Multi-physics problems of an electrotechnic system deal with several subproblems of which the physical nature differs, e.g. electromagnetic, thermal and mechanical problems. Generally, depending on the importance of the internal interaction, multiphysics problems can be simulated with different strategies. A classical approach consists to solve iteratively the numerical models of the different physical problems. For example, in the case of a magneto-elastic problem, in a first step, the electromagnetic model is solved. In a second step, the elastic model is solved considering the magnetic force calculated by the electromagnetic model. The distribution of the magnetic force enables to determine the deformation of the device and then to solve again the electromagnetic model with new conditions. This procedure is repeated until the convergence of both models
