DPM convergence. HELP!

I am trying to simulate laminar bubbly flow in vertical pipes using DPM provided in Fluent.I have defined my own body forces and drag force using UDF and the two-way coupling is considered. After I got the converged continuous phase flow field, I add the bubble injections with body and drag forces. The computation haven't been converged after about 30,000 iterations and the iteration process seems run into a circulation.

Hope anyone who has experience in DPM calculation can give me some suggestions!!

Thank you!!!
