[lammps-users] How to use LAMMPS to simulate particles' adsorption on a free surface?

Many thanks for your advices!

But I have a question concerning this method(Steve): if aveforce was used on the top wall, what is the pressure from bulk phase? is it F/S where F and S are the average force and area of the top wall respectively?

With best regards,


See the doc page for the command - you specify
the force. So if you want pressure, then yes, that's
force per area.
