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-temperature superconducting (HTS) pancake coils in 3-dimensions. FiQuS/Pancake3D can perform magnetodynamic or coupled magneto-thermal simulations. [...]

Magneto-Thermal Thin Shell Approximation for 3D Finite Element Analysis of No-Insulation Coils
/ Schnaubelt, Erik (CERN ; Darmstadt, Tech. U.) ; Atalay, Sina (CERN ; Bogazici U.) ; Wozniak, Mariusz (CERN) ; Dular, Julien (CERN) ; Geuzaine, Christophe (Liege U.) ; Vanderheyden, Benoît (Liege U.) ; Marsic, Nicolas (Darmstadt, Tech. U.) ; Verweij, Arjan (CERN) ; Schöps, Sebastian (Darmstadt, Tech. U.)
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 to meshing difficulties which result in either poor quality mesh elements resulting in a decrease of the solution accuracy or a high number of degrees of freedom. We proposed to mitigate this issue by collapsing the T2TCL volume into a surface and using a so-called thin shell approximation (TSA). [...]

The application of high-temperature superconductors to accelerator magnets for future particle colliders is under study. Numerical methods are crucial for an accurate evaluation of the complex dynamical behavior of the magnets, especially concerning the magnetic field quality and thermal behavior. [...]

Efficient Reduced Magnetic Vector Potential Formulation for the Magnetic Field Simulation of Accelerator Magnets
/ D'Angelo, Laura A.M. (Darmstadt, Tech. U.) ; Moll, Dominik (Darmstadt, Tech. U.) ; Vitrano, Andrea (CERN) ; Marsic, Nicolas (Darmstadt, Tech. U.) ; Schnaubelt, Erik (Darmstadt, Tech. U. ; CERN) ; Wozniak, Mariusz (CERN) ; De Gersem, Herbert (Darmstadt, Tech. U.) ; Auchmann, Bernhard (PSI, Villigen)
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 are modeled by thin wires, whose source field is included into the simulation model along Biot-Savart's law. [...]

A 2-D Finite-Element Model for Electro-Thermal Transients in Accelerator Magnets

Superconducting accelerator magnets require sophisticated monitoring and means of protection due to the large energy stored in the magnetic field. Numerical simulations play a crucial role in understanding transient phenomena occurring within the magnet, and can, therefore, help to prevent disruptive consequences. [...]
