The current work deals with the modelling strategies for the improvement of coupled electromagnetic thermomechanical problems due to induced large deformations or displacements. We introduce a sequentially-coupled algorithm that includes two types of mesh management models. The methodology enables automatic switching between the mesh management models in order to balance computational time and results accuracy.
