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…
Distributed Inter-Strand Coupling Current Model for Finite Element Simulations of Rutherford Cables
Julien Dular, Alexander Glock, Arjan Verweij +1
In this paper, we present the Distributed Inter-Strand Coupling Current (DISCC) model. It is a finite element (FE) model based on a homogenization approach enabling efficient and a…
Acceleration of Multi-Scale LTS Magnet Simulations with Neural Network Surrogate Models
Louis Denis, Julien Dular, Vincent Nuttens +3
While the prediction of AC losses during transients is critical for designing large-scale low-temperature superconducting (LTS) magnets, brute-force finite-element (FE) simulation…
Reduced Order Hysteretic Flux Model for Transport Current Homogenization in Composite Superconductors
Alexander Glock, Julien Dular, Arjan Verweij +1
In this paper, we present the Reduced Order Hysteretic Flux (ROHF) model to describe the relationship between time-varying transport current and internal magnetic flux for composit…
High Field Magnet Programme -- European Strategy Input
B. Auchmann, E. Todesco, A. Ballarino +6
In this submission, we describe research goals, implementation, and timelines of the High Field Magnet Programme, hosted by CERN. The programme pursues accelerator-magnet R&D with…
Reduced Order Hysteretic Magnetization Model for Composite Superconductors
Julien Dular, Arjan Verweij, Mariusz Wozniak
In this paper, we propose the Reduced Order Hysteretic Magnetization (ROHM) model to describe the magnetization and instantaneous power loss of composite superconductors subject to…
