Hi, I have a pressure outlet boundary condition, and some air is passing through it.

I have a target to reach for CFD validation purposes, which is 40 kg /m^2 /s

How do I actually monitor mass flux through my surface in CFX?

If I monitor the expression massFlow@outlet it gives me kg /s and not my needed kg /m^2 /s

There isn't a mass flux variable either.

Is there a simple solution to this please?

Opaque will become famous soon enough
You can monitor massFlow@Outlet / area@Outlet, that is the mass flux.
