Dear Colleagues.
It might be overly simple question, but does anyone know how to construct a cylinder with arbitrary axis (like, (1,1,1)) ?
As far as I know, LAMMPS provides command on axis only parallel to coordinate axis.
thanks in advance.
If you mean a cylinder of atoms at an orientation,
then see the lattice command and its orient option
to set the crystal orientation of the atoms themselves.
Then when you create_atoms you can do it in a region
which is a cylinder and the cylinder can be rotated to
some direction via the region rotate option.
Think of it in 2 steps. You are filling a geometric
volume and the filling is done by putting atoms
on lattice points where the lattice can also be
arbitrarily oriented.
