[lammps-users] Applying the shear force

Dear lammps users,

I am trying to apply the shear force on the finite size structure.
(no PBC)

Anyone knows how to do this?

I tried 'fix addforce' command, but it doesn't work properly.

Thanks in advance.

Drag some boundary atoms sideways. Fix aveforce
or fix setforce, or just giving them a constant velocity
with no force should do this.
