is it possible to use the surface tension option with the Parrinello algorithm (the manual says it is not) ?
I have been using the surface-tension with the Berendsen p couple in a DPPC bilayer, but my system behaves in a strange way:
the use of -200 bar.nm or +200 bar.nm leads to a contraction in the XY plane (I would expect -200 bar.nm to contract and +200 bar.nm to expand the xy area).
I have used either cut-off and PME electrostatics. I have set the compressibility to 9.8e-5 bar-1 in xy and z.
Any suggestion will be very helpful.
