Created 0 atoms

Hello,i run the simulation of below,the simulaiton is work well,but it create 0 atoms in lattices.I have read theregion command,it he
coundn’t solve the problem, so i want to know the reason.

Your region is probably outside the simulation box
due to the difference between box and lattice units.
See the region doc page for details.
