Is there any possibility to create polycrystalline on LAMMPS?

Hello everybody,

I want to create polycrystalline of ferrite. Can I do that with LAMMPS?

Best of luck,

You can create bicrystals or similar simple
geometries by using the lattice command and
create_atoms command multiple times.

For true poly-crystals, you need to create
that geometry with some external program and
write the atom coords to a data file that
LAMMPS reads in via the read_data command.

I know such builders exist - maybe someone else
can post names and links to them.
