This is an abstract for a presentation given at the
Sixth Foresight Conference on Molecular Nanotechnology.
There will be a link from here to the full article when it is available on the web.


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.
