I know this error from using too large timestep. Which timestep do you use?
Mit freundlichen Grüßen

Betreff: namd-l: Re: NPT equilibration
After repeating the npt bequilibration with different no. of steps(500000)
and margin to 2.5 I am getting following error:-
ERROR: Constraint failure in RATTLE algorithm for atom 3343!
ERROR: Constraint failure; simulation has become unstable.
ERROR: Exiting prematurely; see error messages above.
I didn't get that error during nvt simulation which I did for some 20000
steps and I don't know why this error has come...
