A simple, direct derivation and proof of the validity of the SLLOD equations of motion for generalized homogeneous flows
We present a simple and direct derivation of the SLLOD equations of motion for molecular
simulations of general homogeneous flows. We show that these equations of motion (1)
generate the correct particle trajectories,(2) conserve the total thermal momentum without
requiring the center of mass to be located at the origin, and (3) exactly generate the required
energy dissipation. These equations of motion are compared with the g-SLLOD and p-
SLLOD equations of motion, which are found to be deficient. Claims that the SLLOD …
