Different fields at times t=0.23, t=0.44, and t=0.82 in a simulation with driven turbulence. First panel: dust (solid lines) and gas (dotted lines) density fluctuations. Second panel: x-wise dust (solid) and gas (dotted) Mach number. Third panel: magnetic pressure gradient. Fourth panel: total (x, y, z-wise) dust Alfvénic Mach number. Parameters: n_H=10⁶ cm⁻³, s_d=10 μm(St=0.01) and β=1.
