Sorry for not mentioning my question very clearly.
I want interaction energy of water molecules inside nanotube.since
my nanotube is in water box so water inside tube will have contribution
from both nanotube and water outside nanotube.
It is widely quoted in literature water loses energy when it goes
inside nanotube,I want to quantify energy loss.
