Hello , Please I have a question, I am doing simulation for multiphase centrifugal pump 3d. I have velocity inlet boundary condition and pressure outlet boundary. I use population balance model. and I have to insert bin-fraction values: I filled it in the inlet boundary condition but the question is how to fill it in the outlet boundary condition, I mean I fill it with the same values of inlet boundary condition. I attached the picture.

The second question is how to define the backflow interfacial area concentration.

Please, if anyone could help, ?
