When creating a new bond in a LAMMPS simulation with the command fix/bond create it is likely new angles/dihedrals/impropers be need to be set. This can be done with the atype/dtype/itype arguments however, these arguments seem to only take one integer value. I have models where many types of angles or dihedrals could be created from the formation of one new bond. How do you set multiple of these types at once, and specify which new angle/dihedral belongs to which type?

    $\begingroup$ +1. Nice first question! In case you were not yet aware, we also have a LAMMPS chat room here: chat.stackexchange.com/rooms/109805/lammps $\endgroup$ – Nike Dattani Jul 24 at 16:01

    $\begingroup$ @Matt have you considered looking into LAMMPS official mailing list regarding the same issue? $\endgroup$ – SaiSmaran S B PES1201701189PES Jul 25 at 3:56
  • $\begingroup$ I wonder what's happened with this question. Is it something that is answered on the LAMMPS official mailing list? Is it something that Matt has now asked there? Personally I think this site is better suited for Q/A than the older "mail list" concept. $\endgroup$ – Nike Dattani Jul 28 at 1:01
