Contacts, motion and chain-breaking in a two-dimensional granular system displaced by an intruder

These files contain an example of the setup required to perform and analyze a numerical simulation of the motion of an intruder within a two-dimensional granular system. The simulation is carried out using the open-source free DEM software LIGGGHTS. Specifically, we make use of the 3.1.0 version to interact with the DESIgn code, that allows us to perform two-dimensional simulations considering cylindrical particles. The dataset contains an example case of the initialization, simulation, Octave and Matlab codes for post-processing the results, and the code implemented in LIGGGHTS to introduce basal friction effects.
