We study various test scenarios that are aimed at the reproduction of different morphological features observed on comet 67P/Churyumov-Gerasimenko (hereafter 67P) and other small Solar system bodies. For this purpose, we simulate the surface layer regolith dynamics using the discrete element method (DEM). While the immediate objective is to calibrate the mechanical properties of the regolith grains at the particle-particle level such that they imply the macroscopic observables, the long-term aim is to include sublimation and recondensation of volatiles as well as water ice rheology in the simulations in order to better understand outburst triggers and other volatile-related activity.
