Explicit Turn Resolution with Anisotropic Homogenisation for Efficient 3D Magneto-Thermal Finite-Element Simulation of Large-Scale No-Insulation HTS Magnets
Louis Denis, Erik Schnaubelt, Julien Dular +3
No-insulation (NI) and metal-insulation (MI) high-temperature superconducting (HTS) magnets require three-dimensional (3D) models to describe the current distribution around critic…
Surface Contact Approximation for Magneto-Thermal Finite Element Analysis of No-Insulation HTS Coils
Erik Schnaubelt, Louis Denis, Mariusz Wozniak +2
High-temperature superconducting (HTS) coated conductors (CCs) can be wound into no-insulation (NI) coils, in which electrical current can partially bypass local normal zones via t…

Emma Vancayseele, Erik Schnaubelt, Louis Denis +3
Understanding the thermal behaviour of superconducting accelerator magnets is essential to ensure their stable and reliable operation. This work presents an extension of the Finite…
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…
Simulation of Rutherford Cable AC Loss and Magnetization with the Coupled Axial and Transverse Currents Method
Julien Dular, Fredrik Magnus, Erik Schnaubelt +2
The coupled axial and transverse currents (CATI) method was recently introduced to model the AC loss and magnetization in twisted composite superconducting strands with low computa…
Influence of Critical Current Distribution on Operation, Quench Detection and Protection of HTS Pancake Coils
Mariusz Wozniak, Erik Schnaubelt, Sina Atalay +5
High-temperature superconductor (HTS) coated conductors (CC) are often wound into pancake coils with electrical insulation in-between the turns. The copper terminals are used for c…
Mortar Thin Shell Approximation for Analysis of Superconducting Accelerator Magnets
Robert Hahn, Erik Schnaubelt, Mariusz Wozniak +2
Thin layers can lead to unfavorable meshes in a finite element (FE) analysis. Thin shell approximations (TSAs) avoid this issue by removing the need for a mesh of the thin layer wh…
Parallel-in-Time Integration of Transient Phenomena in No-Insulation Superconducting Coils Using Parareal
Erik Schnaubelt, Mariusz Wozniak, Julien Dular +3
High-temperature superconductors (HTS) have the potential to enable magnetic fields beyond the current limits of low-temperature superconductors in applications like accelerator ma…

In this paper, we propose the Coupled Axial and Transverse currents (I) (CATI) method, as an efficient and accurate finite element approach for modelling the electric and magnetic…
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…
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…
Efficient Reduced Magnetic Vector Potential Formulation for the Magnetic Field Simulation of Accelerator Magnets
Laura A. M. D'Angelo, Dominik Moll, Andrea Vitrano +5
The major advantage of reduced magnetic vector potential formulations (RMVPs) is that complicated coil structures do not need to be resolved by a computational mesh. Instead, they…
A Comparison Between Different Formulations for Solving Axisymmetric Time-Harmonic Electromagnetic Wave Problems
Erik Schnaubelt, Nicolas Marsic, Herbert De Gersem
In many time-harmonic electromagnetic wave problems, the considered geometry exhibits an axial symmetry. In this case, by exploiting a Fourier expansion along the azimuthal directi…
