I have a 2d case of a Perforated pipe inside a porous zone. Is there any way to calculate the (mass) flux on the interior wall between fluid and porous zones?(red arrows) [how much fluid is entering the porous zone?]
In the fluent this wall is under the "Internal" tab in BC and I am not able to chose it when calculating the flux.

If the holes have a face ID (interior) then you can report data on that. From memory the interior facets don't store a normal so you may need to align them, /define/boundary-conditions/modify-zones/orient-face-zone should solve that.

Should I run the command before initialization and then run the calculation again?
The first try gave the message:
"Error: 47 contiguous regions in thread. This compromises the ability to orient faces consistently, you may need to separate the face zone to get consistent orientation."
So I tried:
and it broke the initial face into 47 faces (one for each hole).
And now trying
"/define/boundary-conditions/modify-zones> orient-face-zone" for each of those 47 faces is not making them available for flux calculation yet.

If they're interiors they should be available. If not you may need to use either expressions or custom field functions to calculate the mass flow.
