Efficient smoothed particle radiation hydrodynamics II: Radiation hydrodynamics [PDF]
Journal of Computational Physics, 2021 The radiation hydrodynamics equations for smoothed particle hydrodynamics are derived by operator splitting the radiation and hydrodynamics terms, including necessary terms for material motion, and discretizing each of the sets of equations separately in time and space.

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

Smooth Particle Hydrodynamics Simulation of Micro-Cup-Extrusion Using a Graphit-ic Coating
Advances in Materials Science and Engineering, 2014 Microextrusion is becoming increasingly important for the manufacturing of microcomponents. However, this reduction in scale to a microlevel means that the influence of friction and the need for suitable lubrication are greatly increased.

Ionizing radiation in smoothed particle hydrodynamics [PDF]
Monthly 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.
