I know that from the beginning. That's why I found very strange the increasing on the system volume. My initial setup have a density of ~400g/L, and for liquid chloroform is ~1400g/L. Using gromacs-4.5 I get densities of about 200 after 750ps simulation time, and using 4.0 I get almost 500 after 1n
