GADGET-4 is a massively parallel code for N-body/hydrodynamical cosmological simulations. It is a flexible code that can be applied to a variety of different types of simulations, offering a number of sophisticated simulation algorithms. An account of the numerical algorithms employed by the code is given in the original code paper, subsequent publications, and this documentation.

GADGET-4 was written mainly by Volker Springel, with important contributions and suggestions being made by numerous people, including Ruediger Pakmor, Oliver Zier, and Martin Reinecke.
