[http://www.fos.su.se/~sasha/mdynamix/ MDynaMix] is a general purpose [[molecular dynamics]] code for simulations of [[mixtures]] of either rigid or [[flexible molecules]], interacting by a [[Force fields |force field]] consisting of [[Lennard-Jones model |Lennard-Jones]], electrostatic, covalent bonds, angles and torsion angles potentials as well as of some optional terms, in a [[Boundary conditions |periodic rectangular, hexagonal or truncated octahedron cell]]. Rigid bonds are constrained by the [[SHAKE]] algorithm. In case of flexible molecular models the [[double time step algorithm]] is used. Algorithms for [[Microcanonical ensemble |NVE]], [[Canonical ensemble |NVT]] and [[Isothermal-isobaric ensemble |NpT]] statistical [[Ensembles in thermostatistics |ensembles]] are implemented, as well as [[Ewald sum]] for treatment of the electrostatic interactions. Treatment of quantum correction to the atomic motion can be done within the [[Path integral formulation |path integral molecular dynamics]] approach.

Package works on ''Unix/Linux'' workstations and clusters of workstations as well as on ''Windows'' in sequential mode.
