GADGET: A code for cosmological simulations of structure formation

Abstract:
GADGET computes gravitational forces with a hierarchical
tree algorithm and represents fluids by means of smoothed
particle hydrodynamics. The code can be used for studies
of isolated systems, or for simulations that include the
cosmological expansion of space, both with or without
periodic boundary conditions. In all these types of
simulations, GADGET follows the evolution of a
self-gravitating collisionless N-body system (dark matter,
stars), and allows gas dynamics to be optionally included.
Both the force computation and the time stepping of GADGET
are fully adaptive, with a dynamic range which is, in
principle, unlimited. GADGET is a freely available code
for cosmological N-body/SPH simulations on serial
workstations, or on massively parallel computers with
distributed memory. The parallel version of GADGET uses an
explicit communication model that is implemented with the
standardized MPI communication interface.
