Simulated motion of cylindrical woody debris travelling along a straight flume using the DualSPHysics modelling framework

The simulations were carried out using DualSPHysics, an open source SPH-based modelling framework. Four flow conditions with an initial particle diameter equal to 0.008 m were simulated. For each flow condition, three different initial orientations of the woody debris (0, -5 and +5 deg) were tested. The .xml files are the input for the DualSPHysics numerical simulations, they contain all the information needed to set up the simulations and were generated following the guidance provided with DualSPHysics. All the elements needed to define the simulation, namely fluid domain geometry, solid boundaries, and buffer zones for inlet/outlet are described in .vtk files which can be read by Paraview. The motion of the woody debris at each time step is contained in an output CSV file. Further details are provided in the ReadMe.docx.
