Thank you, At the end the problem was solved just increasing the time coupling constant of the barostat tau_p. The original value of 0.15 that I set at the beginning was too small, with 0.5 works fine. On Tue, 09 Oct 2012 14:05:43 -0400 Justin Lemkul wrote: On 10/9/12 11:31 AM, juan-man

I have not much experience with Gromacs, although I have worked for years on molecular simulations. I am trying to run a NPT simulation of 1000 SPCE water molecules at 293 K with the opls force field. I equilibrated the system first during 1 ns using a velocity rescale thermostat, a Berendsen
