Dear Group Members,
I am doing shear flow of granular material between two walls, now i am planning to change my walls (from flat walls) to Bumpy wall (wall with frozen particles). I would appreciate some body please guide me how to do that (which command to use and if possible a input file)?

Thanks in advance!!!

Fix freeze will zero the forces, but not the velocities of atoms.
So if you setup your wall to be moving initially, that will do
what you want.
