MeCN box simulation on MDynaMix package

MDynaMix (an acronym for Molecular Dynamics of Mixtures) is a general purpose molecular dynamics code for simulations of mixtures of either rigid or flexible molecules, interacting by a force field consisting of Lennard-Jones, electrostatic, covalent bonds, angles and torsion angles potentials as well as of some optional terms, in a 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 NVE, NVT and NpT statistical 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 molecular dynamics approach. Package works on Unix/Linux workstations and clusters of workstations as well as on Windows in sequential mode.
