How does molecular dynamics work
http://www.cchem.berkeley.edu/chem195/_molecular_dynamics.html WebDec 30, 2016 · This technique, known as steered molecular dynamics (SMD), allows one to observe slow events within the accessible time scale of MD simulations. However, due to the non-equilibrium nature of the trajectories, in analyzing results one faces the problem of irreversible work that has to be discounted.
