A question about "population balance model (DQMOM)"

Hi everyone.
I have some questions about Fluent by using DQMOM in a eulerian-eulerian approach.
(1) My simulation is a gas-solid flow, solid phase is the secondary phase and only one material. But in DQMOM, I have to input three secondary phases. Do I have to create three phases with the same characteristics? When I define where the granular phase is, which phase do I use ?
(2) How can I initialize for using DQMOM? I have already patched the solid volume fraction, and I output the solid-property-diameter, but I cannot get my correct mean diameter, so what else do I need to do? I cannot figure out the meaning of QDMOM-m4-0 in the initialization.
These have been bothering me for a long time. Thank you very much!!!

Also, I don't understand what the three phases in DQMOM refer to separately
