Hi,

Here are my comments from what I understand: coalesced particles are actually removed trajactories. If you want to track coalesced particles, you can use say DPM_SPRAY_COLLIDE, loop into the particles, check if some became bigger and mark or note them. You can check the UDF manual which uses this macro for a very simple coalescence model..
