Well, yes that will scale the box size to give a certain density.
However, if that is not the correct number of molecules for that particular solvent model, under the conditions you run it, then with NVT you will end up with voids and a negative pressure, and with NPT the box size will decrease until it reaches the appropriate density.

Subject: [gmx-users] Regarding Density
Please somebody tell me in what way the gromacs calculate the density for given no. of molecules and volume of the box. I generated solvent box using genbox_d command line. Is it right that I can scale the solvent box according to density of my interest after generating box using genbox_d command line?
