Smoothed Particle Hydrodynamics Stability Analysis

Journal of Computational Physics, 1995
SPH (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 ...

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, 2007
Smoothed 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.

Curvilinear smoothed particle hydrodynamics

International Journal for Numerical Methods in Fluids, 2016
SummaryWe 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.

AN OVERVIEW ON SMOOTHED PARTICLE HYDRODYNAMICS

International Journal of Computational Methods, 2008
This paper presents an overview on smoothed particle hydrodynamics (SPH), which is a meshfree, particle method of Lagrangian nature. In theory, the interpolation and approximations of the SPH method and the corresponding numerical errors are analyzed. The inherent particle inconsistency has been discussed in detail.

Smooth particle hydrodynamics

2008
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

Smoothed Particle Hydrodynamics Method

2018
In this chapter, the basic concepts of the SPH method and its application in the discretization of the continuum domain in particles are presented. The SPH approximations of the equations of conservation are deduced and explained. Kernels used in interpolations, temporal integration methods, the particle inconsistency problem and numerical corrections ...

ON PARTICLE WEIGHTED METHODS AND SMOOTH PARTICLE HYDRODYNAMICS

Mathematical Models and Methods in Applied Sciences, 1999
This 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.
