Report mass flow on surface along specified vector
 

Hello, i have a cylindrical geometry axial direction z, radial r = sqrt(x^2+y^2) with highly unsteady flow with variations depending on the radius and axial position.



I have defined planes at different radial positions as iso surfaces of specified value of radial coordinate and have then cut them for different axial positions along the z-axis ending up with many iso-clip surfaces.



Now i want to make massflow reports for each iso-clip surface but i dont want the absolute massflow over the surface. Due to the unsteady nature of the problem, the surfaces have flow in both r+ and r- direction. As such I want to have separate reports for the massflow in r+ and r- direction.



Can anyone help me with this?
