Thank you very much for your advice... I have tried including dispcorr = enerpres in my mdp file and the density increased a bit in a timescale of 5 ns but it is still far from the value expected for pure water. These are the new results: Statistics over 251 steps [ 0. thru 5000. ps

Hi I just saw the article Temperature Dependence of TIP3P, SPC, and TIP4P Water from NPT Monte Carlo Simulations: Seeking Temperatures of Maximum Density published in Journal of Computational Chemistry, Vol. 19, No. 10, 1179]1186 (1998). It gives 0.985 for SPC at 25 C with different setup...

Dear all I am starting some MD simulations aimed to calculate the volume of a solute in water as a function of the concentration. First I ran a simulation of a box with 4124 SPC water molecules (similar number of molecules that will be later used with my solute) for which I got the following
