The stress–pressure relationship in simulations of MRI-induced turbulence

Some of the simulations were run on the DiRAC Complexity system, operated by the University of Leicester IT Services, which forms part of the STFC DiRAC HPC Facility (www.dirac.ac.uk). This equipment is funded by BIS National E-Infrastructure capital grant ST/K000373/1 and STFC DiRAC Operations grant ST/K0003259/1. DiRAC is part of the UK National E-Infrastructure run. JR and HNL are partially funded by STFC grants ST/L000636/1 and ST/K501906/1. JG acknowledges support from the Max-Planck-Princeton Center for Plasma Physics.
