[gmx-users] Pressure problem in EM simulation

[Mishelle Oña]

Hello!

I have a question about pressure in EM simulation. I am using Steepest descent method in a water polymer system. My pressure gets this value:

Energy                      Average   Err.Est.       RMSD  Tot-Drift
-------------------------------------------------------------------------------
Pressure                   -2843.38         65    162.655   -446.059  (bar)

The pressure value is very weird. Is this normal? or I am doing something wrong?
