Videos From the GPUSPH YouTube channel: Water waves triggered by a landslideSimulation of the landslide and subsequent water waves in a lake Hu and Adams’s multi-phase SPH formulation is used to simulate this strongly coupled liquid-granular problem. A granular rheological model is used to handle the complex behaviour of the landslide. Dynamic Boundary Particles are used. The simulation, that includes 4,640,000 particles of water, 92,000 particles of soil and 2,200,000 boundary particles (6,932,000 total), ran on four GTX1080Ti (12GB). This work is part of a Research Collaboration Agreement between EDF, Laboratoire National d’Hydraulique et Environnement (LNHE), and the National University of Singapore (NUS), Department of Civil and Environmental Engineering.

Mooring is implemented by modifying the forces exerted by the fluid on the structure to include the contribution of the mooring lines, which is obtained by solving semi-analytically for the tension. High-resolution dam breakHigh-resolution (20 million particles) 3D simulation of a dam break with GPUSPH. This simulation uses the Hu & Adams formulation, with Molteni & Colagrossi density diffusion terms and the experimental support for the dummy boundary model from Adami et al.
