Meridional slice at time 400t_in and angle φ = 3π/8 in run M3T10R10. Left panel: density distribution flattened by a factor of (R/r_in)³ (color scale) and orientation of the poloidal velocity field, green (resp., blue) being oriented upward (resp., downward). Right panel: toroidal magnetic field relative to the local mean (color scale) and integral curves of the poloidal magnetic field. The density is maximal at r/r_in ≈ 4.0, 5.6, and 6.9.
