SPH-EXA: Enhancing the Scalability of SPH codes Via an Exascale-Ready SPH Mini-App

open access: yes, 2019
Numerical simulations of fluids in astrophysics and computational fluid dynamics (CFD) are among the most computationally-demanding calculations, in terms of sustained floating-point operations per second, or FLOP/s. It is expected that these numerical simulations will significantly benefit from the future Exascale computing infrastructures, that will ...

An approach to solving the boundary free edge difficulties in SPH modelling: application to a viscous accretion disc in close binaries [PDF]

open access: bronze, 2010
In this work, we propose a SPH interpolating Kernel reformulation suitable also to treat free edge boundaries in the computational domain. Application to both inviscid and viscous stationary low compressibility accretion disc models in Close Binaries (CB)

Understanding laser-metal interaction in selective laser melting additive manufacturing through numerical modelling and simulation: a review

open access: yesVirtual and Physical Prototyping, 2022
Selective laser melting (SLM) is the most used and versatile technique for additively manufactured metallic parts. Due to its unique flexibility in enabling the fabrication of complex geometries, it has received great attention, especially in very ...

Vortex Identification in a Free-Surface Flow Problem Solved Using SPH [PDF]

open access: yesMATEC Web of Conferences, 2022
This article focuses on vortex structure identification methods and their implementation into smoothed particle hydrodynamics (SPH) framework. The most common criteria based on the local velocity gradient tensor analysis like Q-criterion, Δ-criterion ...

A multi-resolution SPH method for fluid-structure interactions [PDF]

open access: yesJournal of Computational Physics, 2019
In this paper, we present a multi-resolution smoothed particle hydrodynamics (SPH) method for modeling fluid-structure interaction (FSI) problems. By introducing different smoothing lengths and time steps, the spatio-temporal discretization is applied ...

Derivation of SPH equations in a moving referential coordinate system [PDF]

open access: yes, 2009
The conventional SPH method uses kernel interpolation to derive the spatial semi-discretisation of the governing equations. These equations, derived using a straight application of the kernel interpolation method, are not used in practice. Instead the
