Undulatory forcing an intruder through granular media: effects of frequency and packing fraction

These files provide an example of the setup required to perform and analyze a numerical simulation of an intruder moving within a two-dimensional granular system under an oscillatory driving force. The simulations are conducted using the open-source DEM software LIGGGHTS, specifically version 3.1.0, coupled with the DESIgn framework, which enables two-dimensional simulations with cylindrical particles. The dataset includes an example of the initialization procedure, the main simulation setup, MATLAB/Octave scripts for post-processing the results, and the modified LIGGGHTS source code used to incorporate basal friction effects.
