[lammps-users] does HCP structure In lammps satisfy the Crystallography definition?

Dear lammps users
I have defined a hcp structure of 128 atoms using lattice hcp command , But I found it’s coordination number is 2 instead of 12 from the rdf analysis. So does HCP structure In lammps satisfy the Crystallography definition?

I would guess your system is either not periodic
or you are not computing the rdf correctly to get
a value of 2.
