[gmx-users] appropriate values fot tau_t and tau_p

[Rolf Erwin Isele-Holder]

Dear all,

I'm trying to receive thermal properties of a LJ liquid by performing a NPT simulation. To ensure the simulation is in the canonic ensemble, I've chosen the Nose-Hoover thermostat and the Parrinello-Rahmann barostat. I performed several runs with different values for tau_t and tau_p. The results showed, that the property which I am looking for depends on the value of these two parameters. Does anybody know, how to chose these values to get fluctuations, which correspond to the canonical ensemble?
