In the electrical engineering field and more generally in electrical industry, the numerical simulation allows to obtain very accurate information about a system behaviour at an early stage of development. For instance, force calculation is a key parameter for electrical machine design for classical devices like turbogenerator, transformers and motors or more recent technologies used in Sustainable Development. Finite element calculations give more or less straighforward approaches to compute these quantities . These approaches strongly depend on the magnetic properties of the part under investigation and its environment (air, magnets, magnetic steel …).
