Variables at the Internal Face
 

Hy every one I set some planes in a 3D simulation as Interior and I would like to have the velocity profile at those planes... via UDF...

As I can see I only have access to the F_FLUX and F_P and F_FLUX give me the mass flow rate through a given face in a face thread. So how can I get the U,V and W velocities at some face?

Does someone know it??

Thanks
