Saturated vapour pressure of pcff water model

Hello everyone,

has anybody attempted to calculate the saturated vapour pressure that the standard water model implemented in the pcff force field gives, preferentially for different temperatures?
I would like to use this as a reference value p0 for further simulations of water adsorption isotherms. As far as I can judge the capabilities of Materials Studio, there does not seem to be a possibility to calculate it with the modules that are currently available, but any hints in this direction would also be highly appreciated.

Thank you, best wishes,
Michael
