Dear friends
I simulated the bubble flow with polydispersed fluid method (DQMOM) in CFX19.0. The below error is appeared. I tried to increase 'Solver Memory Alloc Factor' to 1.5. But, it doesn't work. This seems to have other reasons. Could you please help me?
Grateful for your help!

This is not a memory error. CFX error messages can by very cryptic.

My guess is that you have not defined the size of one of your size groups in the DQMOM model. Check that all your size groups are properly defined.
