Computational Methods for Electric Machines
Advances in Isogeometric Analysis
One of the original visions of Isogeometric Analysis (IgA) was to bridge the gap between computer aided design (CAD) and simulation. Since a smooth CAD geometry is used at the coarsest mesh level, IgA has several advantages. These include sliding interfaces between stator and rotor of an electrical machine without artificial gaps or intersections, and seamless integration with shape optimizations. As a high-order discretization method, IgA allows for fast convergence of the solution. In order to achieve that in practice, advanced techniques are required, like adaptive refinement, advanced and non-standard discretizations, or fast iterative solvers.
