Query: Parallelization of JOREK-STARWALL for non-linear MHD simulations
  including resistive walls (Report of the EUROfusion High Level Support Team
  Projects JORSTAR/JORSTAR2)   Large scale plasma instabilities inside a tokamak can be influenced by the
currents flowing in the conducting vessel wall. This involves non linear plasma
dynamics and its interaction with the wall current. In order to study this
problem the code that solves the magneto-hydrodynamic (MHD) equations, called
JOREK [Huysmans G.T.A. and Czarny O. NF 47, 659 (2007); Czarny O. and Huysmans
G. JCP 227, 7423 (2008)], was coupled [Hoelzl M., et al. Journal of Physics:
Conference Series, 401, 012010 (2012)] with the model for the vacuum region and
the resistive conducting structure named STARWALL [Merkel P., Strumberger E.,
arXiv:150804911 (2015)]. The JOREK-STARWALL model has been already applied to
perform simulations of Vertical Displacement Events (VDEs), Resistive Wall
Modes (RWMs), Quiescent H-Mode, and vertical kick ELM triggering. At the
beginning of the project it was not possible to resolve the realistic wall
structure with a large number of finite element triangles due to the huge
consumption of memory and wall clock time by STARWALL and the corresponding
coupling routine in JOREK. Moreover, both the STARWALL code and the JOREK
coupling routine were only partially parallelized via OpenMP. The aim of this
project is to implement an MPI parallelization to reduce memory consumption and
execution time such that simulations with large resolutions become possible.
