Cylindrical Smoothed Particle Hydrodynamics

Journal of Computational Physics, 1993
Smoothed particle hydrodynamics (SPH) is formulated in two-dimensional axisymmetric coordinates. Starting with a three-dimensional Cartesian representation of SPH, we integrate out the angular component and find a two-dimensional cylindrical description. A smoothed ``particle'' in this formulation becomes a smoothed ``torus''.

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.

Modeling the progressive axial crushing of foam-filled aluminum tubes using smooth particle hydrodynamics and coupled finite element model/smooth particle hydrodynamics [PDF]

Materials & Design, 2008
As alternatives to the classical finite element model (FEM), a meshless smooth particle hydrodynamics (SPH) method, in which the discrete particles represent a solid domain, and a coupled FEM/SPH modeling technique were investigated for the numerical ...

Smoothed Particle Hydrodynamics

Annual Review of Astronomy and Astrophysics, 1992
In 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, 2007
In 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, 2015
In 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, 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 ...

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.

The Equations of Motion of Particles in Smoothed Particle Hydrodynamics

SIAM Journal on Scientific and Statistical Computing, 1991
Detailed 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.
