Particle hydrodynamics with accurate gradients: a comparison of different formulations
S. Rosswog
We compare here several modern versions of SPH with a particular focus on the impact of gradient accuracy. We examine specifically an approximation to the "linearly exact" gradient…
A simple, entropy-based dissipation trigger for SPH
Stephan Rosswog
Smoothed Particle Hydrodynamics (SPH) schemes need to be enhanced by dissipation mechanisms to handle shocks. Most SPH formulations rely on artificial viscosity and while this is w…
Boosting the accuracy of SPH techniques: Newtonian and special-relativistic tests
S. Rosswog
We study the impact of different discretization choices on the accuracy of SPH and we explore them in a large number of Newtonian and special-relativistic benchmark tests. As a fir…
Special-relativistic Smoothed Particle Hydrodynamics: a benchmark suite
S. Rosswog
In this paper we test a special-relativistic formulation of Smoothed Particle Hydrodynamics (SPH) that has been derived from the Lagrangian of an ideal fluid. Apart from its symmet…
