Lennard-Jones potential

[′len·ərd ′jōnz pə‚ten·chəl]
(physical chemistry)
A semiempirical approximation to the potential of the force between two molecules, given by v = (A / r 12) - (B / r 6), where r is the distance between the centers of the molecules, and A and B are constants.

As a result, the interactions between the DPD particles are not directly based on a Lennard-Jones potential, but are typically subject to three types of forces, namely, conservative forces, dissipative forces, and a random force.
