An Open-Source 3D FE Quench Simulation Tool for No-Insulation HTS Pancake Coils
Sina Atalay, Erik Schnaubelt, Mariusz Wozniak +4
A new module, Pancake3D, of the open-source Finite Element Quench Simulator (FiQuS) has been developed in order to perform transient simulations of no-insulation (NI) high-temperat…
Arbitrary order spline representation of cohomology generators for isogeometric analysis of eddy current problems
Bernard Kapidani, Melina Merkel, Sebastian Schöps +1
The eddy current problem has many relevant practical applications in science, ranging from non-destructive testing to magnetic confinement of plasma in fusion reactors. It arises w…
Magneto-Thermal Thin Shell Approximation for 3D Finite Element Analysis of No-Insulation Coils
Erik Schnaubelt, Sina Atalay, Mariusz Wozniak +6
For finite element (FE) analysis of no-insulation (NI) high-temperature superconducting (HTS) pancake coils, the high aspect ratio of the turn-to-turn contact layer (T2TCL) leads t…
Reduced Basis Approximation for Maxwell's Eigenvalue Problem and Parameter-Dependent Domains
Max Kappesser, Anna Ziegler, Sebastian Schöps
In many high-frequency simulation workflows, eigenvalue tracking along a parameter variation is necessary. This can become computationally prohibitive when repeated time-consuming…
Deep learning based Meta-modeling for Multi-objective Technology Optimization of Electrical Machines
Vivek Parekh, Dominik Flore, Sebastian Schöps
Optimization of rotating electrical machines is both time- and computationally expensive. Because of the different parametrization, design optimization is commonly executed separat…
Data-Driven Update of B(H) Curves of Iron Yokes in Normal Conducting Accelerator Magnets
Luisa Fleig, Melvin Liebsch, Stephan Russenschuck +1
Constitutive equations are used in electromagnetic field simulations to model a material response to applied fields or forces. The characteristic of iron laminations depends…
Combination of Measurement Data and Domain Knowledge for Simulation of Halbach Arrays with Bayesian Inference
Luisa Fleig, Melvin Liebsch, Stephan Russenschuck +1
Accelerator magnets made from blocks of permanent magnets in a zero-clearance configuration are known as Halbach arrays. The objective of this work is the fusion of knowledge from…
A Stabilized Circuit-Consistent Foil Conductor Model
Elias Paakkunainen, Jonas Bundschuh, Idoia Cortes Garcia +2
The magnetoquasistatic simulation of large power converters, in particular transformers, requires efficient models for their foils windings by means of homogenization techniques. I…
Low-Frequency Stabilization of Dielectric Simulation Problems with Conductors and Insulators
Devin Balian, Melina Merkel, Jörg Ostrowski +2
When simulating resistive-capacitive circuits or electroquasistatic problems where conductors and insulators coexist, one observes that large time steps or low frequencies lead to…
