Numerical data for "Force distribution within a barchan dune"

This dataset contains information from numerical simulations on the distribution of forces within a subaqueous barchan dune. The files contain information of the contact forces between two particles (in contact force 0.5 s folder), and the resultant force acting on each particle (in total force 1.5 s folder) forming a barchan dune under the action of a turbulent water flow.本数据集包含针对水下新月形沙丘（subaqueous barchan dune）内部力分布的数值模拟相关数据。其中，接触力0.5s文件夹中存储了构成该沙丘的颗粒间的接触力（contact force）信息，总力1.5s文件夹中则存储了湍流水流（turbulent water flow）作用下各颗粒所受的合力（resultant force）信息。
