LES-DEM computations of barchan dunes

These files contain the 20 first seconds of results of a CFD-DEM simulation of a barchan dune formation and the codes used to analyze those results. The simulation was carried out using the open-source free CFDEM software, which couples the open-source CFD code OpenFOAM with the open-source DEM code LIGGGHTS. The simulations were tested and the results agreed quite well with the expected results from the literature. The dataset contains the results of an example case, from both the DEM and the CFD sides, and we also share the full Octave code for post-processing those results.
