This project proposes the application of a Spline or more precisely NURBS-based finite element approach for the simulation of electrical machines, the so-called isogeometric analysis. This novel approach promises accurate solutions with a low number of degrees of freedom and enables elegantly to model geometry variations due to the Spline parametrisation, e.g. within an uncertainty quantification or shape optimisation of a machine. The movement of the rotor is implemented by mortaring in a saddle-point formulation. We propose novel approaches based on Splines and spectral elements which will be analyzed theoretically and practically.
