The correct representation of the particle shape plays an important role in coupled CFD-DEM simulations. The combination of spherical and all kinds of nonspherical particles with advanced drag models allows for an accurate depiction of the interaction of bulk materials and fluids.
Modelling of the wave attenuation by flexible vegetation. Due to the flow resistance caused by the vegetation the wave pattern as well as the erosion pattern on the bottom is affected.
