Numerical modelling of extreme waves by Smoothed Particle Hydrodynamics [PDF]
Natural Hazards and Earth System Sciences, 2011 The impact of extreme/rogue waves can lead to serious damage of vessels as well as marine and coastal structures. Such extreme waves in deep water are characterized by steep wave fronts and an energetic wave crest.

SMOOTHED PARTICLE HYDRODYNAMICS SIMULATIONS USING GRAPHICS PROCESSING UNITS
TASK Quarterly, 2014 Smoothed Particle Hydrodynamics (SPH) is a fully Lagrangian, particle-based technique for fluid-flow modeling. As a gridless method, it appears to be a natural approach to simulate multi-phase flow with complex geometries. Since SPH involves a large set

Hybrid smoothed particle hydrodynamics [PDF]
Proceedings of the 2011 ACM SIGGRAPH/Eurographics Symposium on Computer Animation, 2011 We present a new algorithm for enforcing incompressibility for Smoothed Particle Hydrodynamics (SPH) by preserving uniform density across the domain. We propose a hybrid method that uses a Poisson solve on a coarse grid to enforce a divergence free velocity field, followed by a local density correction of the particles.
