Local evolution of the different species with column densities normalized by the initial dust column density versus time. Left panel: scenario 1 configuration where collisional dust can grow back to (primordial) pebbles, and reach an equilibrium state. Right panel: scenario 2 configuration, where compact collisional dust can not grow pebble sizes. This simulation was done using the default parameter set R = 10 AU, Mdisk = 0.01 M and ɛ = 0.1.
