MD wall interaction

#1 Post by amd » Tue Oct 02, 2012 2:28 pm

Hi,
I have a basic question. I was wondering if anyone could please let me know its answer.
we know that the atoms interact with each other according to a force-field based on namely LJ potential but there is not any viscous force that reduce the relative velocity of pairs. So, if we apply an external force along the nano channel, we expect that the atoms accelerate and their velocities increase infinitely. I wanna know what is the origin of formation of a Poiseuille velocity profile and not a plug flow?
Thank you
AMd
