Dear LAMMPS Community:
I am going to use the Fix bond/create to create bonds between atom type_1 and atom type_2. Type_1 is in molecule_1 (say, carbon in methylene group) and type_2 is in molecule_2 (say, carbon in benzene). The goal is to link two molecules of type molecule_2 together via creating two covalent bonds between atom types type_2 and type_1 (like this {type_2 ---- type_1 ----- type_2}). The question is how to avoid creating such bond in an individual molecule? For example, how can I avoid the creation of bonds between two carbon atoms as type_2 in one single benzene molecule and a carbon atom as type_1 in methylene group?
Any help would be greatly appreciated.
