The vertical structure of the simulations, where x is the radial direction and z is the vertical direction. The left and right columns correspond to simulations with (τ_s, Z) = (0.01, 0.03) and (0.03, 0.005), respectively. The top row is the dust-to-gas ratio ϵ. The second, third, and last rows correspond to the radial, azimuthal, and vertical components (A_x, A_y, and A_z), respectively, of the aerodynamic flow A. The gray regions are where ϵ < 10⁻⁵. The black contours show where ϵ = 1 and 10. Since the dust is highly settled, the horizontal axis covers much more length than the vertical axis for easier visualization.
