[lammps-users] which command can do this?

Hi all,

I was wondering which command can be used to apply a displacement of a region or group of atoms. For example, my model have two parts: top and bottom, I want to rigid shear the top relative to the bottom. For each shear step, only a small displacement of top part are applied. This may be very easy to implement but I could’t find the corresponding command. Your input is highly appreciated. Thanks!

Best,

AC

The shear example that is packaged with LAMMPS (at least the versions I have downloaded in the past) does this.
