Collaborative behavior of intruders moving amid grains

These files contain an example of the configuration required to run and analyze a numerical simulation of the motion of a set of intruders within a two-dimensional granular system. The simulation is performed using the DEM open source software LIGGGHTS. Specifically, we use version 3.1.0 combined with the DESIgn toolbox (Agnieszka Herman, Geosci. Model Dev., doi:10.5194/gmd-9-1219-2016), which allows us to perform two-dimensional simulations considering cylindrical particles. The data set contains an example case of the initialization of the system, the actual simulation of the motion of the intruders, Octave and Matlab codes for post-processing the results, a code implemented in the DESIgn toolbox to insert basal friction effects in the simulations, and some videos of the actual simulations.
