Are heuristic switches necessary to control dissipation in modern smoothed particle hydrodynamics ?
Domingo García-Senz, Rubén M. Cabezón
Artificial viscosity is commonly employed in smoothed particle hydrodynamics (SPH) to model dissipation in hydrodynamic simulations. However, its practical implementation today rel…

From particles to precision. Simulating subsonic turbulence with Smoothed Particle Hydrodynamics
Rubén M. Cabezón, Domingo García-Senz, Oliver Avril +6
The numerical simulation of subsonic turbulence with smoothed particle hydrodynamics (SPH) has traditionally been hampered by zeroth-order (E0) errors, inaccurate gradient evaluati…

Do not forget the electrons: Extending moderately-sized nuclear networks for multidimensional hydrodynamic codes
Domingo García-Senz, Rubén M. Cabezón, Moritz Reichert +5
We present here an extended nuclear network, with 90 species, designed for being coupled with hydrodynamic simulations, which includes neutrons, protons, electrons, positrons, and…
