Advanced Isogeometric Framework for the Analysis of Electric Drives
This research project is a part of the Collaborative Research Centre (CRC) Computational Electric Machine Laboratory. In this first German-Austrian Transregio CRC, research groups from TU Darmstadt, JKU Linz, and TU Graz want to achieve a paradigm shift in the design and development of electrical machines.
An accurate geometric representation is an absolute must for reliable computational simulations, especially for electrical drives where the air gap between the stator and rotor is crucial. The project will use the isogeometric paradigm combined with level-set functions to enable an advanced discretisation framework that addresses this challenge. Thereby, it provides fundamental routines for the novel space-time and optimisation methods developed in other projects of this CRC. Finally, the exchange and subsequent editing of the optimised shapes is enabled by generating analysis-suitable boundary representations compatible with current CAD standards.
