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.
