Parameter space study of dust mass in the disk. Top and middle rows: The mass of small and grown dust in the disk (the red and blue solid lines) as a function of time for the fiducial model (top left) and for models with varying free parameters as indicated in each panel. Bottom rows: The ratio of enclosed dust masses M_d,gr (r)∕M_d,sm(r) as a functionof radial distance r at two evolution times: t = 0.2 Myr and t =0.4 Myr, for the fiducial model and for models with varying free parameters.
