### GADGET-2

(an n-body/SPH simulation computer program)

**GADGET-2** is the current version (as of 2013) of **GADGET**,
a computer program for N-body simulation and
smoothed-particle hydrodynamics.
It was written by Volker Springel at the
Max Planck Institute for Astronomy.

*GADGET* uses a hierarchical tree to compute
gravitational forces and represents fluids (gas, plasma)
using SPH. It can be used to model the
large scale structure of the universe
or for smaller phenomena such as galaxy collisions
and mergers.
**GADGET-1** was released in 2000 and GADGET-2 in 2005.
