swift - v2025.01

Version of SWIFT from January 2025.

Major changes since v1.0.0: - Removed engine_marktasks() and the duplicated task unskipping infrastructure. - Added the option to use adaptive softening for some flavours of the hydro. - Added more physics to the sink particles, including an adaptive smoothing length (search radius). - Added more examples using sink particles. - Updated the configuration scripts to select good compiler options with Intel OneAPI. - Added the option for the star formation models to spawn >1 star particle per star formation event (super-sampling). This can be switched on in the EAGLE model. - Reduced the number of communications of end-of-step messages and replaced them by a all-reduce. - Added the option to run GEAR-RT on top of SPHENIX SPH. - Many updates to the AGN spin-jet model (See the Husko+2024 paper for details) - Many updates to the GEAR model.

swift -

• Added adaptive multipole acceptance criterion for gravity alongside the fixed opening angle,
• Rewritten the time integration of the large-scale periodic forces coming from the PM calculation to reach the expected level of accuracy in the large-scale matter power-spectrum in precision cosmology runs,
• Added an implementation of the Phantom SPH scheme (hydro only),
• Made the SPHENIX SPH scheme the default hydro model,
• Added a cooling subgrid model using the Ploeckinger+2020 tables,
• Added a Quick-Lyman-alpha mode for cosmological simulations,
• Added the option to not compute the gravitational potentials,
• Added the option to store sub-halo orphan particles computed by VELOCIraptor,
• Added a mode to store snapshots in multiple sub-files when running over MPI,
• Added the option to select the fields to write or not in the snapshots at runtime,
• Added the option to apply lossy compression filters to select fields in the hdf5 outputs,
• Extended the meta-data in the snapshots including all relevant runtime parameters and particle locations in the files for quick access,
• Fixed an old bug with the long-range gravity calculation in non-periodic non-cosmological mode that lead to a segfault in large planetary calculations,
• Expanded the EAGLE and GEAR subgrid models,
• Added the ANEOS equations of state for planetary calculations,
• Reduced the memory footprint over MPI,
• Large number of small fixes and speed improvements
