GROMACS is a versatile package to perform molecular dynamics, i.e. simulate
the Newtonian equations of motion for systems with hundreds to millions of
particles.
.
It is primarily designed for biochemical molecules like proteins and lipids
that have a lot of complicated bonded interactions, but since GROMACS is
extremely fast at calculating the nonbonded interactions (that usually
dominate simulations) many groups are also using it for research on non-
biological systems, e.g. polymers.
