From particles to precision. Simulating subsonic turbulence with Smoothed Particle Hydrodynamics
Rubén M. Cabezón, Domingo GarcÃa-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…

GPU-Native Compressed Neighbor Lists with a Space-Filling-Curve Data Layout
Felix Thaler, Sebastian Keller
We have developed a compressed neighbor list for short-range particle-particle interaction based on a space- filling curve (SFC) memory layout and particle clusters. The neighbor l…

Tidal disruption events with SPH-EXA: resolving the return of the stream
Noah Kubli, Alessia Franchini, Eric R. Coughlin +4
In a tidal disruption event (TDE), a star is disrupted by the tidal field of a massive black hole, creating a debris stream that returns to the black hole, forms an accretion flow,…
