  Future e-mobility calls for efficient electrical machines. For different
areas of operation, these machines have to satisfy certain desired properties
that often depend on their design. Here we investigate the use of multipatch
Isogeometric Analysis (IgA) for the simulation and shape optimization of the
electrical machines. In order to get fast simulation and optimization results,
we use non-overlapping domain decomposition (DD) methods to solve the large
systems of algebraic equations arising from the IgA discretization of
underlying partial differential equations. The DD is naturally related to the
multipatch representation of the computational domain, and provides the
framework for the parallelization of the DD solvers.
