What is "gromos"

GROMOS is a force field for molecular dynamics simulation developed at the University of Groningen and at Computer-Aided Chemistry Group at the Laboratory for Physical Chemistry at the ETH Zurich. At the University of Groningen Herman Berendsen was involved in its development.

The united atom force field was optimized with respect to the condensed phase properties of alkanes.

GROMOS is also the name for the molecular dynamics simulation package associated with this force field.
