Thermal Model Calibration of a Squirrel-Cage Induction Machine
Leon Blumrich, Christian Bergfried, Armin Galetzka +4
Accurate and efficient thermal simulations of induction machines are indispensable for detecting thermal hot spots and hence avoiding potential material failure in an early design…
Robust Adaptive Least Squares Polynomial Chaos Expansions in High-Frequency Applications
Dimitrios Loukrezis, Armin Galetzka, Herbert De Gersem
We present an algorithm for computing sparse, least squares-based polynomial chaos expansions, incorporating both adaptive polynomial bases and sequential experimental designs. The…
A multilevel Monte Carlo method for high-dimensional uncertainty quantification of low-frequency electromagnetic devices
Armin Galetzka, Zeger Bontinck, Ulrich Römer +1
This work addresses uncertainty quantification of electromagnetic devices determined by the eddy current problem. The multilevel Monte Carlo (MLMC) method is used for the treatment…
Multilevel Monte Carlo Simulation of the Eddy Current Problem With Random Parameters
Armin Galetzka, Zeger Bontinck, Ulrich Römer +1
The multilevel Monte Carlo method is applied to an academic example in the field of electromagnetism. The method exhibits a reduced variance by assigning the samples to multiple mo…
