[gmx-users] box volume and solvant density

Dear all,

I am running simulations of pure water at various temperatures. My first
step is an annealing from the previous temperature to the next one,
using a NPT ensemble. Using the result of that, I run an NVT simulation.

Where can I recover the box average box dimensions, volume and density
of water in the NVT run ?
Using g_density, I am surprised to find that the density is varying by
several percent; shouldn't it remain constant ?

Thanks in advance for your insights
