Snapshots of the density (black/white) and the field-parallel mass flux (green/pink colors) in the evolved state of variants of run β1ι45 shown in Fig. 4. The panels show the effect of a) a bigger computational box, b) a doubled resolution, c) a doubled resolution and explicit shear viscosity, d) a doubled resolution and explicit magnetic diffusivity. The plots include selected magnetic field lines, the scale height (solid horizontal lines), and the sonic surface (dashed lines).
