SMOOTHED PARTICLE HYDRODYNAMICS FOR WATER WAVES
Volume 5: Ocean Space Utilization; Polar and Arctic Sciences and Technology; The Robert Dean Symposium on Coastal and Ocean Engineering; Special Symposium on Offshore Renewable Energy, 2007Smoothed Particle Hydrodynamics provides a numerical method particularly well suited to examine the breaking of water waves due to the ability of the method to cope with splash. The method is a meshfree Lagrangian method that allows the computational domain to deform with the flowing liquid.

Smoothed Particle Hydrodynamics
Annual Review of Astronomy and Astrophysics, 1992In this review the theory and application of Smoothed particle hydrodynamics (SPH) since its inception in 1977 are discussed. Emphasis is placed on the strengths and weaknesses, the analogy with particle dynamics and the numerous areas where SPH has been successfully applied.

Smoothed particle hydrodynamics in complex shapes
Proceedings of the 23rd Spring Conference on Computer Graphics, 2007In this paper, we propose an improved computation model of wall boundary in Smoothed Particle Hydrodynamics, a particle method for fluid simulation. Generally, particle methods calculate a wall boundary by converting it to wall particles. The proposed method uses a distance function calculated from a polygon model as a wall boundary. As a result, fluid

Divergence-free smoothed particle hydrodynamics
Proceedings of the 14th ACM SIGGRAPH / Eurographics Symposium on Computer Animation, 2015In this paper we introduce an efficient and stable implicit SPH method for the physically-based simulation of incompressible fluids. In the area of computer graphics the most efficient SPH approaches focus solely on the correction of the density error to prevent volume compression. However, the continuity equation for incompressible flow also demands a

Smoothed Particle Hydrodynamics Stability Analysis
Journal of Computational Physics, 1995SPH (smoothed particle hydrodynamics) is a gridless Lagrangian technique which is appealing as a possible alternative to numerical techniques currently used to analyze large deformation events. A von Neumann stability analysis of the SPH algorithm has been carried out which identifies the criterion for stability or instability in terms of the stress ...

ON PARTICLE WEIGHTED METHODS AND SMOOTH PARTICLE HYDRODYNAMICS
Mathematical Models and Methods in Applied Sciences, 1999This paper deal with designing of weighted particle approximation of conservation laws. New ideas concerning the use of variable smoothing length, renormalization and the use of Godunov type finite difference fluxes in particle methods are introduced and discussed in connection with standard implementation of the SPH method.

The Equations of Motion of Particles in Smoothed Particle Hydrodynamics
SIAM Journal on Scientific and Statistical Computing, 1991Detailed attention is given to the derivation of the equations of motion in smoothed particle hydrodynamics (SPH). It is rigorously shown that the four-dimensional divergence of the momentum density can be replaced by the total derivative with respect to time of the unsmoothed particle velocity.

Curvilinear smoothed particle hydrodynamics
International Journal for Numerical Methods in Fluids, 2016SummaryWe suggest a new set of equations to employ smoothed particle hydrodynamics (SPH) in a curvilinear space, and we refer to it as curvSPH. In classical SPH, the horizontal and vertical resolution of discretization is supposed to be equal for fluid particles. However, curvSPH makes the horizontal and vertical resolutions independent from each other.

This paper reviews a possible alternative to the traditional mesh-based hydrodynamic approach. The technique is Smooth Particle Hydrodynamics (SPH). SPH was first applied by Lucy [1] to the problem of rotating star bifurcation, and subsequently developed, tested, and extended by Monaghan and coworkers [2]. SPH is a gridless Lagrangian technique that is
