Abstract

We describe a major update to the public GIZMO code. GIZMO has been used in simulations of cosmology; galaxy and star formation and evolution; black hole accretion and feedback; proto-stellar disk dynamics and planet formation; fluid dynamics and plasma physics; dust-gas dynamics; giant impacts and solid-body interactions; collisionless gravitational dynamics; and more. This release of the public code supports: hydrodynamics (using various mesh-free finite-volume Godunov methods or SPH), ideal and non-ideal MHD, anisotropic conduction and viscosity, radiative cooling and chemistry, star and black hole formation and feedback, sink particles, dust-gas (aero)-dynamics (with or without magnetic fields), elastic/plastic dynamics, arbitrary (gas, stellar, degenerate, solid/liquid material) equations of state, passive scalar/turbulent diffusion, large-eddy and shearing boxes, self-gravity with fully-adaptive force softenings, arbitrary cosmological expansion, and on-the-fly group-finding. It is massively-parallel with hybrid MPI+OpenMP scaling verified up to >1 million threads. The code is extensively documented, with test problems and tutorials provided for these different physics modules.

Additional Information:We thank Volker Springel both for his personal mentoring, and for writing GADGET, without which GIZMO would not exist. We also thank the large number of GIZMO code developers who have contributed to the content in the public code, especially Daniel Angles-Alcazar, Xiangcheng Ma, Shea Garrison-Kimmel, Mike Grudic, Alessandro Lupi, Robert Thompson, Quirong Zhu, Hongping Deng, Dusan Keres, and Paul Torrey. Support for PFH and GIZMO development was provided by an Alfred P. Sloan Research Fellowship, NSF Collaborative Research Grant #1715847 and CAREER grant #1455342, Caltech compute cluster “Wheeler,” allocations from XSEDE TG-AST130039 and PRAC NSF.1713353 supported by the NSF, and NASA HEC SMD-16-7592.
