[lammps-users] Can "bond_style harmonic" not work with "atom_style atomic" ?

hi,
I set atom_style be atomic and bond_style harmonic.
lmp returns :
ERROR: Bond_style command when no bonds allowed
(bond_style harmonic between read_data )
OR

ERROR on proc 0: No bonds allowed with this atom style
(bond_style harmonic after read_data )

After I change atom_style to “full”, it works.

Is it a bug? Or any reason?

Thank you!

Atom style atomic doesn't let you define bonds.
Other atom styles do. See the atom_style doc
page for details.

Steve, get it!
Thank you for your reply!
I will read the manual more carefully!
