I am having all 4 pressure values in positive sign and values are high (ex
one time output : 2519186.3001 2519187.5205 2518108.1341 2518107.9413).
Then definitely my average should be in the same range. Then how can i get
my target pressure 1.03125 bar?

>>> Dear All,
>>> For NPT simulation, I am using Langevin dynamics in
>>> namd and parameters are given below
>>> useGroupPressure on
>>> useFlexibleCell yes
>>> useConstantArea yes
>>> langevinPiston on
>>> langevinPistonTarget 1.01325
>>> langevinPistonTemp 300
>>> langevinPistonDecay 300
>>> langevinPistonPeriod 300
>>> How can I check, If my system reached 1.01325 bar or not? since output
>>> pressure has many values. Kindly help me in this.
