Hi,
Your problem is equivalent to applying a given pressure along z and a
nonzero surface tension along x/y (assuming nearly constant cell height Lz).
You should be able to achieve that using SurfaceTensionTarget.
Pz is then specified by LangevinPistonTarget,and I think the surface
tension should be Lz * (Pz - 1 bar).
