Hi Alex,

I think you're best off describing the wall with particles. You can
freeze them to a specific position (make it a freeze-group) and set
all interactions between them to zero. You can tune your particles to
be hydrophilic or hydrophobic.

Hope it helps,

Tsjerk

I would like to make a slit-like smooth pore, to calculate adsorption of some
small peptides from liquid water on the pore walls. Hydrophilicity or
hydrophobicity of the walls should be tunable.
