Computational Methods and Applied Mathematics
TimeTuesday, June 3013:45 – 15:45 CEST
LocationBldg. 6 – 003
DescriptionOrganizer(s): Eric Sonnendrücker, Florian Hindenlang (Max Planck Institute for Plasma Physics), and Stephan Brunner (EPFL)
Nuclear fusion is considered a credible complement to renewable energies in the effort towards reaching sustainable development goals. The currently most advanced and promising fusion reactor devices are the tokamak and the stellarator, which are based on the concept of magnetic confinement. Due to the high cost of building such machines as well as the complexity of the processes involved, comprehensive numerical simulations with a substantial HPC component are indispensable to progress our understanding of the underlying physics. This minisymposium is dedicated to the development and application of first-principle kinetic and gyrokinetic codes. As these models are computing a 5D or 6D distribution function, the codes will need very large computational resources so that special attention needs to be taken to optimize as well the algorithms as their implementation. The four talks will be dedicated to performance and optimization of the CGYRO gyrokinetic code for multiscale plasma turbulence simulation, to the development of the new exascale semi-Lagrangian gyrokinetic code GYSELA-X++ with first benchmarks and physics results, to the development of a new geometric Particle-In-Cell code GEMPICX based on the AMReX framework and to global gyrokinetic simulation with the flux-tube code Stella.
