Custom flow in molecular dynamics

Driving an inertial many-body system out of equilibrium generates complex dynamics due to memory effects and the intricate relationships between external driving force, internal forces, transport effects. Understanding underlying physics is challenging often requires carrying case-by-case analysis. To systematically study interplay all types forces that contribute dynamics, a method generate prescribed flow patterns could be great help. We develop custom numerically construct force field required obtain desired time evolution system, as by its one-body current density profiles. validate in Newtonian purely repulsive particles creating slow motion out-of-equilibrium process prescribing full two distinct states. The can also used with thermostat algorithms control temperature.
