Mass of solids remaining at the end of each simulation as a function of the initial solid mass. Simulations from the planetesimal accretion scenario are shown in the left panel whilst those from the pebble accretion scenario are shown in the right panel. All solids lost include those that have been ejected from the system and lost to the central star. The dashed linesshow the 25, 50, 75 and 100% margins. The colour coding in both panels corresponds to similarity criterion (Eq. (11)).
