Software
GROMACS
GROMACS (GROningen MAchine for Chemical Simulations) is a molecular dynamics and energy minimization package mainly designed to simulate the Newtonian equations of motion for systems with hundreds to millions of particles, typically of proteins, lipids and nucleic acids. GROMACS can run on CPUs and GPUs.
MOLDY
Moldy is a C program for performing molecular-dynamics simulations of solids and liquids using periodic boundary conditions. The model system is completely specified in a run-time input file and may contain atoms, molecules or ions in any mixture. Molecules or molecular ions are treated in the rigid-molecule approximation and their rotational motion is modeled using quaternion methods. The equations of motion are integrated using a modified form of the Beeman algorithm. Simulations may be performed in the usual NVE ensemble or in isobaric and/or isothermal ensembles. Potential functions of the Lennard–Jones, 6-exp and MCY forms are supported and the code is structured to give an straightforward interface to add a new functional form. The Ewald method is used to calculate long-ranged electrostatic forces.
