Hi All,
I am doing 2d simulation of Yukawa liquid. I want to make a wall only for ylo surface.
How i make interaction potential between wall and particles Yukawa.

you can use any of the wall fixes in LAMMPS, if that is the kind of
wall you want, or you can build one from explicitly placing particles
and immobilizing them.
