[gmx-users] Meaningless pressure values: NVT and NVE ensembles

[Mark Abraham]

Hi,

Tiny systems will take a long time to show a converged value of pressure.
See http://www.gromacs.org/Documentation/Terminology/Pressure. No
observation of pressure in Gromacs is meaningful without mention of the
length of post-equilibration measurement time and the error estimate gmx
energy provides.
