Time evolution of the grown dust-to-gas mass ratio ζ_gr and the total dust-to-gas mass ratio ζ in the x − z slice for the $a_{\text{max }}^{\text{cap}}$ = 100 μm model. The left and right groups of panels show ζ_gr and ζ, respectively. White color indicates the initial value of log ζ_gr = −2.51 and shades of red correspond to dust enhancements. Time is measured from the disk formation epoch, which occurs 193 kyr after the onset of the simulations.
