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…
Electro-thermal topology optimization of an electric machine by the topological derivative considering drive cycles
Nepomuk Krenn, Théodore Cherrière, Sebastian Schöps +1
We consider a 2d permanent magnet synchronous machine operating in a sequence of static operating points coming from a drive cycle. We aim to find a rotor design which maximizes th…
Transient Finite Element Simulation of Accelerator Magnets Using Thermal Thin Shell Approximation
Erik Schnaubelt, Andrea Vitrano, Mariusz Wozniak +3
Thermal transient responses of superconducting magnets can be simulated using the finite element (FE) method. Some accelerator magnets use cables whose electric insulation is signi…
Isogeometric Analysis for 2D Magnetostatic Computations with Multi-level Bézier Extraction for Local Refinement
Andreas Grendas, Michael Wiesheu, Sebastian Schöps +1
Local refinement is vital for efficient numerical simulations. In the context of Isogeometric Analysis (IGA), hierarchical B-splines have gained prominence. The work applies the me…
