Numerical Simulation of Barchans interacting with dune-size obstacles

The dataset consists of the setup to reproduce a simulation of a subaqueous barchan interacting with an obstacle. 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 dataset contains a complete example of a by-pass case. Additionally, we share all Octave codes used for post-processing the results.
