Many thanks from your help. In the manual at the
section g_energy has been written that the gromacs calculate the delta G
as is follows:
"Delta G = G(N,p,T) - G idgas(N,p,T) = kT ln < eˆ(Upot/kT) >"
I don't understand why Upot? to calculate of delta S, I know that
"delta S = (internal energy + P*delta V- delta G)/T" but here has been
written: Delta S(N,p,T) = S(N,p,T) - S idgas(N,p,T) = (<Upot> + pV
- Delta G)/T.
May I ask you to answer me about this and the equation of delta G, Please?
