Incorrect generation of structure?

Hello all,
I am generating a block of lithium with the (110) plane oriented in the z-direction. The following simple code deck is used, but as you can see in the image, the entire block doesn’t seem to be generated. Are there glaring issues causing this? Running on 08Feb2023, and using KOKKOS with 1 MPI task and 4 OpenMP threads.

units metal

atom_modify sort 0 0

Sometimes if a lattice point lies exactly on the boundary of the input region to create_atoms, an atom may or may not be generated on it, because of floating point math; you may want to define your region such that every lattice point is (say) 0.5 angstrom within the boundary, and see if that makes a difference.

@srtee is correct. I recently had exactly this same issue (again).

You can also use region atoms block INF INF INF INF 0.99 11.1 which uses lattices units directly.

Shifting the region boundaries is one possible way to address the ambiguity of placing atoms on region boundaries. Another, often more convenient one, is to shift the origin of the lattice by a small distance, e.g. to 0.1 0.1 0.1: lattice command — LAMMPS documentation

Thanks for the help, I have my complete structure now.
