There are three inlets(inlet1,inlet2,inlet3) and five outlets in the analysis model .
I want to get the mass flow which comes from inlet1 for one of five outlets,how to get this result in the post-CFX or how to realize in the pre-CFX?

Thanks for your answer.

Put a passive scalar scalar in the flow (in CFX talk an additional variable with a convection equation only, or maybe convection+diffusion) which tags the inlet you are interested in and get its concentration at the outlet of interest.

I think some of the tutorials use a additional variable. Also look it up in the documentation.
