Topology optimisation of electric machines: quest for global optima
Peter Gangl, Michael Winkler
Johann Radon Institute for Computational and Applied Mathematics (RICAM)
It is well-known that real-world topology optimisation problems often exhibit multiple local minima and that derivative-based methods are prone to getting stuck in a possibly suboptimal local solution. We present a way of computing multiple locally optimal solutions to topology optimisation and illustrate the method for a two-pole synchronous reluctance machine.
