Integrating High Performance In-Memory Data Streaming and In-Situ Visualization in Hybrid MPI+OpenMP PIC MC Simulations Towards Exascale
Jeremy J. Williams, Stefan Costea, Daniel Medeiros +11
Efficient simulation of complex plasma dynamics is crucial for advancing fusion energy research. Particle-in-Cell (PIC) Monte Carlo (MC) simulations provide insights into plasma be…
First global gyrokinetic profile predictions of ITER burning plasma
A. Di Siena, C. Bourdelle, A. Bañón Navarro +11
In this work, we present the first global gyrokinetic simulations of the ITER baseline scenario operating at 15 MA using GENE-Tango electrostatic and electromagnetic simulations. T…
Machine Learning for Electron-Scale Turbulence Modeling in W7-X
Ionut-Gabriel Farcas, Don Lawrence Carl Agapito Fernando, Alejandro Banon Navarro +2
Constructing reduced models for turbulent transport is essential for accelerating profile predictions and enabling many-query tasks such as parameter exploration and design optimiz…
The impact of plasma turbulence on atomic reaction rates in the detached ASDEX Upgrade divertor
Konrad Eder, Wladimir Zholobenko, Andreas Stegmeir +2
Numerical modeling of the edge and scrape-off layer (SOL) must account for atomic processes such as hydrogenic ionization and recombination, charge-exchange, and line radiation. Th…
On the mechanism of Pedestal Relaxation Events -- Insights gained by turbulence simulations with GRILLIX
Christoph Pitzal, Andreas Stegmeir, Tim Happel +7
Pedestal Relaxation Events (PREs) appear in I-mode discharges close to the I-H transition. Although they show certain similarities with Edge Localised Modes (ELMs), i.e. periodic e…
Multiscale turbulence in stellarators
G. Merlo, A. Bañón Navarro, T. Görler +2
We present the first gyrokinetic simulations of multiscale turbulence in a stellarator, using the magnetic geometry of Wendelstein 7-X (W7-X) and experimentally relevant parameters…
Turbulence and Transport in Spectrally Accelerated full-f Gyrokinetic Simulations
B. J. Frei, P. Ulbl, C. Pitzal +2
We investigate edge and scrape-off layer (SOL) turbulence and transport using the spectrally accelerated full-f gyrokinetic (GK) code GENE-X, recently introduced in [B. J. Frei et…
