lattice custom Command for non-orthogonal lattice

Dear lammps experts,

I am going to make a model with a non-orthogonal lattice in LAMMPS but I cannot understand where I can insert the lattice angels!

As I understood, I should first define a PRISM region for the simulation box. Am I right?

Any comment is highly appreciated.

Best regards,

LAMMPS does not use angles, it uses the edge
vectors of a triclinic box which are the a1,a2,a3
vectors of the lattice custom command. Section 8.3.2 of
the manual discusses how to transferm
between different representations of
a triclinic box, including a discussion of angles.
