|
|
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, lipids and nucleic acids 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.
|
|
|
|
GROMACS supports all the usual algorithms you expect from a
|
|
modern molecular dynamics implementation, (check the online
|
|
reference or manual for details), but there are also quite a
|
|
few features that make it stand out from the competition.
|
|
|
|
See: http://www.gromacs.org/About_Gromacs for details.
