>Dear community,
>
>Pasted below are a sample of my output energies. I am concerned by
>the pressure readings. I have read in a previous thread that it is
>normal for the pressure to jump around a lot (I am using an NVT
>ensemble), but these values seem rather excessive to me, since I used
>a water and lipid box which (I believe) was equilibarated to 1bar.
>Would anyone give me feedback on whether they think that these
>pressures negatively affect my simulation?
>
>Thanks in advance!!
>Best wishes,
>Charles
