| ('''GRO'''ningen '''MA'''chine for '''C'''hemical '''S'''imulations) is a versatile package to perform [[molecular dynamics]], i.e. simulate the
| |
| [[Newtons laws |Newtonian equations of motion]] for systems with hundreds to millions of particles.
| |
| GROMACS is primarily designed for [[Biological systems |biochemical molecules]] like [[proteins]] and [[lipids]] that have a lot of complicated bonded interactions, but since GROMACS is extremely fast at calculating the non-bonded interactions (that usually dominate simulations) many groups are also using it for research on non-biological systems, e.g. [[polymers]].

| ==GROMACS on Tesla GPUs==
| |
| The CUDA port of GROMACS enabling GPU acceleration is now available in beta and supports [[Ewald sum#Particle mesh|Particle-Mesh-Ewald]], arbitrary forms of non-bonded interactions, and implicit solvent Generalized Born methods <ref> source: [http://www.nvidia.com/object/gromacs_on_tesla.html NVIDIA]</ref>
| |
| ==Constraint algorithms==
| |
| GROMACS can use either the [[SHAKE]] or the [[LINCS]] algorithms <ref>[http://www.gromacs.org/@api/deki/files/82/=gromacs4_manual.pdf GROMACS 4 Manual] § 3.6 </ref>.
| |
| ==Force fields==
| |
| GROMACS comes with the following [[force fields]] <ref>Source: /usr/share/gromacs/top for gromacs-4.5.5 </ref><ref>GROMACS 4.5.6 manual § 4.10 </ref>
