Andreas Stegmeir (Max Planck Institute for Plasma Physics): Application of code coupling in magnetic fusion

Abstract:
Nuclear fusion technology is projected to play a major role as a source of clean and safe energy in the future. the process of converting complex physical theories to working engineering applications, modelling and simulation assumes a vital position. While simulating nuclear fusion devices, the physical and geometrical complexity arising from different scales and physical regimes needs to be addressed. In this talk opportunities of coupling methods for solving the multiphysics and multiscale problems of magnetic fusion will be presented. As a first application the coupling of a code simulating the core region of a tokamak with the code GRILLIX simulating turbulent transport in the edge region is considered. To perform this coupling, a partitioned black‐box approach is pursued using the open‐source coupling library preCICE. The main focus is on the geometrical complexities of the coupling arising due to the usage of different coordinates in both participants.
