Numerical Simulation of Barchan-barchan repulsion

The dataset shared within these files consists of the full setup to perform a numerical simulation of a subaquous barchan-barchan dune interaction. 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 previously tested and validated (considering only one single barchan dune) against experimental results and results from the literature. The dataset contains a complete example case. We also share the full Octave code for post-processing those results. To understand and run the case, the user should be noticed that previously experience with both OpenFOAM and LIGGGHTS are recommended.
