Description

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.

Files

Steps to reproduce

1) In the folder "contact force 0.5 s" are files containing the contact, normal and tangential forces that resulted from the collisions of particles in the dune during the first 0.5 seconds of simulation. Each file was saved at every 5000 time steps being the DEM interval time t = 5 x10^-6 s. The Matlab's script to access the information of these files is available as Reader_contact_force.m. 2) In the folder "total force 1.5 s" are files containing the resultant force acting on each particle forming the dune during the first 1.5 seconds of simulation. Each file was saved at every 5000 time steps being the DEM interval time of 5 x10^-6 s. The Matlab's script to access the information of these files is available as Reader_total_force.m. *Description of the Matlab's scripts are presented in each folder and in the scripts themselves.
