Notes. The target and projectile are homogeneous and feature an intermediate porosity (φ = 0.35). These simulations have been carried out to show how the proposed model can quantitatively demonstrate the results of pre-planetesimal collisions. Each simulation is assigned a broad categorisation so that the transition regions between the categories can be investigated.
