stress on the 111 plane of FCC

Hi Everybody

I am looking to create a FCC structure in 111 plane in order to create the Interface and I would like to apply stress on the structure .Could you please tell how can I apply stress using lammps in perpendicular direction?

With the lattice orient command and create_atoms
and region command you can create atoms on a lattice
in any orientation you wish and fill fairly arbitrary volumes,
e.g. the region filled can be oriented as well.

You can apply stress via straining a system with the
displace_box or fix deform commands.

So it's up to you to figure out how to setup the geometry
you want.
