Hi guys

I tried to simulate a air-water column in FLUENT with Euler model that coupled with Population Blance equation and standard K-epsilon for turbulance model but I get a lots of AMG divergence errors... it is done in 3D and 2D models but it seems that errors are similar
some times it's about Bin fraction of inlet air and some times it is about K and epsilon equation

problem :
unsteady state
a cylinder which air with a specific constant diameter injected with 0.085 m/s
and no sperger is used in inlet and no water in inlet
outlet in pressure outlet and with back flow of 1 for air phase
and one thing ... I used a discrete procedure in PBE with 10 bins diameter

it is necessary that I say a mesh file is edited so much only effect of element is on how soon I get that erros ...

I encountered the same problem. Were you able to solve it.
Please Help
