Dear all,
I have learned that rmsd is a judge of system equilibrium. If rmsd is not changed, then the system should be in equilibrium state. However, when I do
a simulation with an ice box and NPT ensemble, the rmsd is changing even after 500ps. The total energy, average temperature, volume and average pressure are all oscillating in a reasonable way and their average values are indeed the targets. Does this shows that the syetem is in equilibrium state? If it does, why the rmsd curve continues changing? If it doesn't, what's the criteria(s) of equilibrium? I am quite puzzled, I would be grateful if someone could give me some advice.
Best Regards!
yours,
Cong Chen
