Abstract

We consider the theoretical model of Bergmann and Lebowitz for open systems out of equilibriumand translate its principles in the adaptive resolution molecular dynamics technique (AdResS).We simulate Lennard-Jones fluids with open boundaries in a thermal gradient and find excellentagreement of the stationary responses with results obtained from the simulation of a larger, locallyforced closed system. The encouraging results pave the way for a computational treatment of opensystems far from equilibrium framed in a well-established theoretical model that avoids possiblenumerical artifacts and physical misinterpretations.
