DPM volume fraction and phase 2 volume fraction

I am simulating a fluidized bed with Ansys/Fluent 15 DDPM two phases model (no DEM collision). However, only 2 time steps after particles injection, phase 2 volume fraction starts deviating from DPM volume fraction value (cell mean value). I am confused about this. Should these two values be the same or not in order to do a two-coupled simulation?
 Therefore, my simulation always crashes and ends with a over-packing according to DPM volume fraction (~0.7). |
