Simplification of the Isotropic Generalized Stop-Type Prandtl-Ishlinskii Vector Hysteresis Operator Using Analytical Return-Point Mapping
Arvinth Shankar, Klaus Kuhnen, Iryna Kulchytska-Ruchka +1
While the thermodynamically formulated generalized Prandtl-Ishlinskii stop-type operator effectively captures hysteresis nonlinearities, it requires a local iterative procedure to…
Accelerating Industrial Finite Element Simulations of Electric Machines based on Runtime Analysis
Arvinth Shankar, Iryna Kulchytska-Ruchka, Sebastian Schöps
The simulation of electric machines plays a significant role in the design of efficient and competitive products. Faster simulations reduce computational costs, such as CPU hours,…
Efficient Pareto-Front Generation for Electric Machines using IGA and Second Order Derivatives
Theodor Komann, Michael Wiesheu, Stefan Ulbrich +2
The multiobjective optimization of electric machines always involves a trade-off caused by various competing objectives such as performance and cost. A suitable design is usually d…
The CREATOR Project: Towards a Computational Electric Machine Laboratory
Sebastian Schöps, Annette Muetze, Herbert De Gersem +3
The Collaborative Research Centre TRR 361/F90 CREATOR (2022-2030) aims at establishing a new paradigm for the simulation-driven design of electric machines. Increasing demands on e…
Subdivision-based isogeometric analysis for axisymmetric electromagnetic problems
Devin Balian, Sebastian Schöps, Melina Merkel
This paper applies a subdivision-based isogeometric method to solve the axisymmetric Maxwell eigenvalue problem. The reduction to an -formulation allows to use a Catmull-Clark…
A Comparison of Multirate Co-Simulation Techniques for Field-Circuit Coupled Problems
Michael Wiesheu, Sebastian Schöps, Idoia Cortes Garcia
This paper compares three different multirate splitting approaches for the application on field-circuit coupled magnetoquasistatic simulations. For these methods, again three diffe…
