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.本数据集包含于本次提供的文件中，涵盖了用于开展水下新月形沙丘(barchan dune)-新月形沙丘相互作用数值模拟的全套配置方案。本次模拟采用开源免费的CFDEM软件完成，该软件将开源计算流体动力学代码OpenFOAM与开源离散元代码LIGGGHTS进行了耦合。本模拟此前仅针对单个新月形沙丘开展了测试与验证，验证依据为实验结果与已发表文献的研究成果。本数据集包含一套完整的示例算例。我们还提供了用于对上述模拟结果进行后处理的完整Octave代码。若需理解并运行该示例算例，建议使用者具备OpenFOAM与LIGGGHTS的相关使用经验。
