[lammps-users] atom_style

Thanks for your reply.
sorry. I wanted to know about using "atom_style atomic" or "atom_style
molecular" commands


You can use atom_style atomic with Tersoff. The 2-body and 3-body
terms it computes are done in a pairwise computation from the LAMMPS
perspective. Atom_style bond or molecular is when you use explicit
bond, angle, dihedral potentials.
