[lammps-users] Input script for one lattice over another

I was wondering if it is possible for me to put a unit cell or an island of a FCC or HCP lattice over a substrate having a different lattice structure eg. diamond (Si)? If I could do this, I would appreciate if someone could help me with the structure of the input script.

Also, how do I create a wurtzite structure?

Thanks,
Mihir.

You can use the lattice command multiple times and the
create_atoms command multiple times to create as many
sets of atoms as you wish.
