Hi guys !

       I want to know that how to set the system's pressure properly because the pressure not undergo in the expected way .  the pressure values was seted

  as 0.007Gpa but the final pressure of the system was hugely  lager or smaller  than the set values after a NPT simulation .

       Neither anderson nor berendson we choosed to control the pressure that can't get a satisfied results and the same simulation were run for many time ,

  but the pressure always was not steady .

  Wish your replay

  Thanks!
