In this paper, it is demonstrated that classical molecular dynamics
(MD) simulation is not a suitable tool for studying directional and coherent
transmission of mechanical energy at the nanometer size scale in fluid
systems. Essentially, classical dynamics is too chaotic for the meaningful
study of coherence properties, although it is well established to be
suitable for studying phenomena in fluids which are controlled by incoherent
energy transfer and random thermal motion such as viscosity and diffusion
coefficient.
