An improved form of smoothed particle hydrodynamics method for crack propagation simulation applied in rock mechanics

open access: yesInternational Journal of Mining Science and Technology, 2021
The simulation of crack propagation processes in rock engineering has been not only a research hot spot among scholars but also a challenge. Based on this background, a new numerical method named improved kernel of smoothed particle hydrodynamics (IKSPH)

Smoothed particle hydrodynamics and magnetohydrodynamics [PDF]

open access: yesJournal of Computational Physics, 2012
This paper presents an overview and introduction to Smoothed Particle Hydrodynamics and Magnetohydrodynamics in theory and in practice. Firstly, we give a basic grounding in the fundamentals of SPH, showing how the equations of motion and energy can be self-consistently derived from the density estimate.

Smoothed Particle Hydrodynamics in Astrophysics [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 2010
This review discusses smoothed particle hydrodynamics (SPH) in the astrophysical context, with a focus on inviscid gas dynamics. The particle-based SPH technique allows an intuitive and simple formulation of hydrodynamics that has excellent conservation properties and can be coupled to self-gravity with high accuracy.

Modelling free surface flows with smoothed particle hydrodynamics

open access: yesCondensed Matter Physics, 2006
In this paper the method of Smoothed Particle Hydrodynamics (SPH) is extended to include an adaptive density kernel estimation (ADKE) procedure. It is shown that for a van der Waals (vdW) fluid, this method can be used to deal with free-surface phenomena

Ionizing radiation in smoothed particle hydrodynamics [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2000
A new method for the inclusion of ionizing radiation from uniform radiation fields into 3D Smoothed Particle Hydrodynamics (SPHI) simulations is presented. We calculate the optical depth for the Lyman continuum radiation from the source towards the SPHI particles by ray-tracing integration.

Smoothed particle hydrodynamics

open access: yes, 2004
Smoothed Particle Hydrodynamics (SPH) is a unique numerical method widely used for astrophysical problems since it involves no spatial grid. Rather, fluid quantities are carried by a set of Lagrangian `particles' which move with the flow, meaning that complicated dynamics and asymmetric phenomena are treated with ease.

An Intelligent SPH Framework Based on Machine-Learned Residual Correction for Elliptic PDEs

open access: yesAlgorithms
We present an intelligent, non-intrusive framework to enhance the performance of Symmetric Smoothed Particle Hydrodynamics (SSPH) for elliptic partial differential equations, focusing on the linear and nonlinear Poisson equations.
