[gmx-users] Compressibility in lipid membranes

Hello to everybody,
I am performing a simulation of a lipid membrane made of DPPC molecules in a
water solvent and I am fixing certain surface tension.
; Pressure coupling =
Pcoupl = berendsen
Pcoupltype = surface-tension
; Time constant (ps), compressibility (1/bar) and reference P (bar) =
tau_p = 4.0 4.0
compressibility = ? ?
ref_p = 500.0 1.0
However I dont know which compressibility I should fix in each direction.
Could anybody help me with this issue and explain to me why it should be in
such a way?
Thanks in advance!!
