....Newton s second law, M d 2 x dt 2 = Gamma U x ; 8) where M is the mass of the atom. A small damping term needs to be added to the above equation to drive the system to equilibrium (minimum energy) configuration. The equation can be numerically integrated using predictor corrector methods [30, 14, 3, 4]. Thus, the molecular dynamics simulations consist of the following steps: 1. Initialize coordinates x; 2. Predictor step; 3. Compute total energy U = U el U rep ; 4. Compute the forces; 5. Corrector step. Steps 2 through 5 are repeated (usually several hundred times) until all the forces are ....
