Surface density of grown dust with the disk regions susceptible to the streaming instability identified by the black curves. The rows from top to bottom correspond to the fiducial model, model with a lower mass of the prestellar core, and model with a higher value of the viscous parameter. The left column shows the time-dependent evolution of the azimuthally averaged Σ_d,gr , while the right column presents the two-dimensional distribution of Σ_d,gr in the inner 10 × 10 au box at the end of simulations.
