They don't make a great deal of sense at this time in the morning: they've not had breakfast yet! ;)

Rocky takes the Fluent flow, temperature etc over and works the particle motion out. That's then passed back to Fluent. Those interactions shouldn't be needed. 

DPM-averaged is only mentioned for DDPM. Double check you've not turned it on by mistake: Rocky does all of the particle tracking for you but needs the dummy phase in Fluent to hold the data.
