On the computation of analytic sensitivities of eigenpairs in isogeometric analysis
Anna Ziegler, Melina Merkel, Peter Gangl +1
The eigenmodes of resonating structures, e.g., electromagnetic cavities, are sensitive to deformations of their shape. In order to compute the sensitivities of the eigenpair with r…
How to Build the Optimal Magnet Assembly for Magnetocaloric Cooling: Structural Optimization with Isogeometric Analysis
Michael Wiesheu, Melina Merkel, Tim Sittig +5
In the search for more efficient and less environmentally harmful cooling technologies, the field of magnetocalorics is considered a promising alternative. To generate cooling span…
A Spline-based Partial Element Equivalent Circuit Method for Electrostatics
Riccardo Torchio, Maximilian Nolte, Sebastian Schöps +1
This contribution investigates the connection between Isogeometric Analysis (IgA) and the Partial Element Equivalent Circuit (PEEC) method for electrostatic problems. We demonstrat…
Hermite-type modifications of BOBYQA for optimization with some partial derivatives
Mona Fuhrländer, Sebastian Schöps
In this work we propose two Hermite-type optimization methods, Hermite least squares and Hermite BOBYQA, specialized for the case that some partial derivatives of the objective fun…
Multi-Objective Yield Optimization for Electrical Machines using Machine Learning
Morten Huber, Mona Fuhrländer, Sebastian Schöps
This work deals with the design optimization of electrical machines under the consideration of manufacturing uncertainties. In order to efficiently quantify the uncertainty, blackb…
Mode Recognition by Shape Morphing for Maxwell's Eigenvalue Problem
Anna Ziegler, Niklas Georg, Wolfgang Ackermann +1
In electrical engineering, for example during the design of superconducting radio-frequency cavities, eigenmodes must be identified based on their field patterns. This allows to un…
Torque Computation with the Isogeometric Mortar Method for the Simulation of Electric Machines
Melina Merkel, Bernard Kapidani, Sebastian Schöps +1
In this work isogeometric mortaring is used for the simulation of a six pole permanent magnet synchronous machine. Isogeometric mortaring is especially well suited for the efficien…
Performance Analysis of Electrical Machines Using a Hybrid Data- and Physics-Driven Model
Vivek Parekh, Dominik Flore, Sebastian Schöps
In the design phase of an electrical machine, finite element (FE) simulation are commonly used to numerically optimize the performance. The output of the magneto-static FE simulati…
Variational Autoencoder based Metamodeling for Multi-Objective Topology Optimization of Electrical Machines
Vivek Parekh, Dominik Flore, Sebastian Schöps
Conventional magneto-static finite element analysis of electrical machine design is time-consuming and computationally expensive. Since each machine topology has a distinct set of…
