First predictive simulations for deuterium shattered pellet injection in ASDEX Upgrade
M. Hoelzl, D. Hu, E. Nardon +1
First simulations of deuterium shattered pellet injection (SPI) into an ASDEX Upgrade H-Mode plasma with the JOREK MHD code are presented. Resistivity is increased by one order of…
Development and testing of an unstructured mesh method for whole plasma gyrokinetic simulations in realistic tokamak geometry
Z. X. Lu, Ph. Lauber, T. Hayward-Schneider +2
In this work, we have formulated and implemented a mixed unstructured mesh-based finite element (FE)-Fourier decomposition scheme for gyrokinetic simulations in realistic tokamak g…
Testing performance with and without Block Low Rank Compression in MUMPS and the new PaStiX 6.0 for JOREK nonlinear MHD simulations
Richard Nies, Matthias Hoelzl
The interface to the MUMPS solver was updated in the JOREK MHD code to support Block Low Rank (BLR) compression and an interface to the new PaStiX solver version 6 has been impleme…
Simulating the nonlinear interaction of relativistic electrons and tokamak plasma instabilities: Implementation and validation of a fluid model
V. Bandaru, M. Hoelzl, F. J. Artola +2
For the simulation of disruptions in tokamak fusion plasmas, a fluid model describing the evolution of relativistic runaway electrons and their interaction with the background plas…
Numerical study of tearing mode seeding in tokamak X-point plasma
Dmytro Meshcheriakov, Matthias Hoelzl, Valentin Igochine +11
A detailed understanding of island seeding is crucial to avoid (N)TMs and their negative consequences like confinement degradation and disruptions. In the present work, we investig…
Non-linear modeling of the threshold between ELM mitigation and ELM suppression by Resonant Magnetic Perturbations in ASDEX Upgrade
François Orain, M. Hoelzl, F. Mink +9
The interaction between Edge Localized Modes (ELMs) and Resonant Magnetic Perturbations (RMPs) is modeled with the magnetohydrodynamic code JOREK using experimental parameters from…
