Wall lj/93 pbc query

LAMMPS LAMMPS Mailing List Mirror

Dear LAMMPS users,

I would like to have my polymer interact with walls (wall lj/93) on both top and bottom. Is it sufficient to switch on the bottom wall interactions and also pbc ? Or should I explicitly place walls on both top and bottom ?

Thanks

you need two walls and you should turn pbc in that direction off.

Dear Axel,

Thanks for the reply. Can I use the wall on one side only and switch on pbc so that I can use the barostat and have the polymer interacting with walls on both sides.

Thanks

this makes no sense and contradicts the documentation.
also, i already told you what you have to do, why do you insist on
something else? if that were possible, i would have told you.
if you don't want to follow advice, why are you asking for it?
