[gmx-users] Diferent Pressure Solvent

if you simulate adsorption of your molecule at 2 bar and then seal the
tube, then pressure inside tube will be 2 bar. in turn, you can
control pressure outside using the barostat.

though a difference between 1 bar and 2 bar in case of very spatially
small MD systems and therefore huge pressure fluctuations is probably
difficult to capture. maybe 1 bar and 100 bar will make more sense...
