Is there a LIGGGHTS capability to take a particle under given conditions and split it / replace it with several smaller particles? I'm specifically looking for a solution within the "granular" atom-style world (but it could be a hybrid style).
I could have sworn I saw an example of this a few months ago, but I can't find it now. Was this the multisphere capability? (node/20 illustrates multiple particles bonded together, but I want one particle that splits into multiple independent particles).
