Dust-to-gas volume density ratio ρ_d/ρ_g as a function of radius r and height z in simulations of the scenarios SIwhileVSI (top panel) and SIafterVSI (bottom panel) with an initial dust-to-gas surface density ratio of 2% and a dust size of 3 cm. The volume density ratio is depicted at the end of the simulations 10 kyr after the initialisation of the dust particles. The vertical dust distribution in the SIwhileVSI simulation resembles a Gaussian, but is wave-like in the SIafterVSI simulation.
