Dynamics of granular beds undergoing impact and cratering

These files contain an example of the setup required to perform and analyze a numerical simulation of the impact of a projectile on a granular bed. The simulation is carried out using the open-source free DEM software LIGGGHTS. The simulations were tested and the results agreed quite well with the models and experiments from the literature. The dataset contains an example case of the initialization, which requires several steps, and from the main simulation. We also share an Octave code for post-processing the results.
