[gmx-users] water flow

[Alex]

Hi all,

I'm trying to explore pressure-induced processes, i.e. externally induced
water flow across a porous membrane that spans the entire box in XY. There
are obvious choices:

1. Introduce the same type of a membrane without pores and make it a piston
with pull code, e.g. constant force or tiny constant velocity along Z.
2. Apply constant force pull directly to the entire solvent group.

Any other ideas on osmosis-like processes? Has anyone tried any of the
options above?

Thanks,

Alex
