There's no simple answer for that. If you apply a lateral pressure (xy plane) and the system is evacuated in the z direction, the only thing that you might expect is that your system would be squeezed in that direction, and then the lateral pressure would relax.
If you're thinking about a gas exerting a pressure on the interface, your system would need to have a pressurized gas instead of vacuum in the z direction. Please note that pressure would arise from the gas you have put into the box and not from an external pressure bath (I would stick to NVT for such a model). Among the possible issue you might face, the gas would probably be partially miscible in the liquid phase for high pressures. I hope it helps. cheers Andre On Wed, Apr 3, 2013 at 11:07 PM, Elisabeth <[email protected]> wrote: > Hello all, > > Does anyone know how one can study the effect of pressure on surface > tension of pure liquids? > > Thanks, > -- > gmx-users mailing list [email protected] > http://lists.gromacs.org/mailman/listinfo/gmx-users > * Please search the archive at > http://www.gromacs.org/Support/Mailing_Lists/Search before posting! > * Please don't post (un)subscribe requests to the list.
