Full one-fluid dusty gas with multiple grain species in SPH
Mark Hutchison, Guillaume Laibe, Giovanni Tedeschi-Prades +5
We present a Smoothed Particle Hydrodynamics (SPH) implementation of the full one-fluid dusty gas algorithm for multiple dust species, generalising our previous terminal velocity a…

Momentum-conserving self-gravity in the phantom smoothed particle hydrodynamics code. Parallel dual tree traversal for the symmetric fast multipole method
Yann Bernard, Timothée David-Cléris, Daniel J. Price +1
Tree codes that approximate groups of distant particles with multipole expansions are the standard way to accelerate the computation of self-gravity on particles. While momentum-co…

The Shamrock code: I- Smoothed Particle Hydrodynamics on GPUs
Timothée David--Cléris, Guillaume Laibe, Yona Lapeyre
We present Shamrock, a performance portable framework developed in C++17 with the SYCL programming standard, tailored for numerical astrophysics on Exascale architectures. The core…
