Steve:

Here is a simple question about Lammps. I

am trying to create a hcp lattice and rotate it in Lammps. I use the

command lattice hcp 2.93093 orient x 1 0 1 orient y 0 1 0 orient z -8

0

3. It says the orient vectors are not orthogonal. If you take x as a

0

c and z as -8a 0 3c, then the vectors are perfectly orthogonal. What
