Hi Nancy,
Am I right in thinking here that what you mean is you do not want the entire
system solvated? I'm not sure why you would necessarily want this but if I
assume this is what you want to do then you will not be running periodic
boundary simulations I assume. Of course in this case your water will
immediately boil off into vacuum so you will need to use some kind of
solvent cap with a restraint on the edges of the cap. You can do this using
the solvatecap command in leap. You give it a radius for the water to be
added and also a center. By centering it on the end of your tube you should
be able to create a water distribution (albeit spherical) at the end of your
carbon nanotubes.
Good luck,
Ross
