Query: MPI-AMRVAC for Solar and Astrophysics   In this paper we present an update on the open source MPI-AMRVAC simulation
toolkit where we focus on solar- and non-relativistic astrophysical
magneto-fluid dynamics. We highlight recent developments in terms of physics
modules such as hydrodynamics with dust coupling and the conservative
implementation of Hall magnetohydrodynamics. A simple conservative high-order
finite difference scheme that works in combination with all available physics
modules is introduced and demonstrated at the example of monotonicity
preserving fifth order reconstruction. Strong stability preserving high order
Runge-Kutta time steppers are used to obtain stable evolutions in
multidimensional applications realizing up to fourth order accuracy in space
and time. With the new distinction between active and passive grid cells,
MPI-AMRVAC is ideally suited to simulate evolutions where parts of the solution
are controlled analytically, or have a tendency to progress into or out of a
stationary state. Typical test problems and representative applications are
discussed, with an outlook to follow-up research. Finally, we discuss the
parallel scaling of the code and demonstrate excellent weak scaling up to 30
000 processors allowing to exploit modern petascale infrastructure.
