CRKSPH - A Conservative Reproducing Kernel Smoothed Particle Hydrodynamics Scheme

, 2016
We present a formulation of smoothed particle hydrodynamics (SPH) that utilizes a first-order consistent reproducing kernel, a smoothing function that exactly interpolates linear fields with particle tracers.

Thermodynamically admissible form for discrete hydrodynamics

, 1999
We construct a discrete model of fluid particles according to the GENERIC formalism. The model has the form of Smoothed Particle Hydrodynamics including correct thermal fluctuations.

Post‐Newtonian Smoothed Particle Hydrodynamics [PDF]

The Astrophysical Journal, 2001
We introduce an adaptation of the well-known tree+SPH numerical scheme to post-Newtonian (PN) hydrodynamics and gravity. Our code solves the (0 + 1 + 2.5)PN equations. These equations include Newtonian hydrodynamics and gravity (0PN), the first-order relativistic corrections to those (1PN), and the lowest order gravitational radiation terms (2.5PN). We

Smoothed-Particle Hydrodynamics Models: Implementation Features on GPUs

, 2017
Parallel implementation features of self-gravitating gas dynamics modeling on multiple GPUs are considered applying the GPU-Direct technology. The parallel algorithm for solving of the self-gravitating gas dynamics problem based on hybrid OpenMP-CUDA ...

Improving convergence in smoothed particle hydrodynamics simulations without pairing instability

, 2012
The numerical convergence of smoothed particle hydrodynamics (SPH) can be severely restricted by random force errors induced by particle disorder, especially in shear flows, which are ubiquitous in astrophysics.

Conformally Flat Smoothed Particle Hydrodynamics: Application to Neutron Star Mergers

, 2002
We present a new 3D SPH code which solves the general relativistic field + hydrodynamics equations in the conformally flat approximation. Several test cases are considered to test different aspects of the code.
