Neural-Parareal: Dynamically Training Neural Operators as Coarse Solvers for Time-Parallelisation of Fusion MHD Simulations
S. J. P. Pamela, N. Carey, J. Brandstetter +10
The fusion research facility ITER is currently being assembled to demonstrate that fusion can be used for industrial energy production, while several other programmes across the wo…
Implementation of matrix compression in the coupling of JOREK to realistic 3D conducting wall structures
Federico Cipolletta, Nina Schwarz, Matthias Hoelzl +6
JOREK is an advanced non-linear simulation code for studying MHD instabilities in magnetically confined fusion plasmas and their control and/or mitigation. A free-boundary and resi…
RMP screening in JOREK-CARIDDI
Bas Slotema, Matthias Hoelzl, Verena Mitterauer
Edge localized modes (ELMs) are instabilities at the tokamak edge that can have short outbursts of highly energetic particles and heat, which can severely damage the walls of a pla…
Towards Robust Solvers for Nuclear Fusion Simulations Using JOREK: A Numerical Analysis Perspective
Alex Quinlan, Vandana Dwarka, Ihor Holod +1
One of the most well-established codes for modeling non-linear Magnetohydrodynamics (MHD) for tokamak reactors is JOREK, which solves these equations with a Bézier surface based fi…
How well can VMEC predict the initial saturation of external kink modes in near circular tokamaks and stellarators?
Rohan Ramasamy, Matthias Hoelzl, Sophia Henneberg +3
The equilibrium code, VMEC, is used to study external kinks in low tokamaks and stellarators. The applicability of the code when modelling nonlinear MHD effects is explor…
Probing non-linear MHD stability of the EDA H-mode in ASDEX Upgrade
A Cathey, M Hoelzl, L Gil +11
Regimes of operation in tokamaks that are devoid of large ELMs have to be better understood to extrapolate their applicability to reactor-relevant devices. This paper describes non…
