cross section average
 

Hi

I am really stuck at the moment with a 3D Fluent UDF. For an equation i need to imput, i need to know at each cross section the average axial velocity of the section. So the sum of each axial velocity devided by the area. Which can then be read into the equation. Having gone through the froum search function there apears to be a solution but not specific to this and my level of skill is not capable of determing the next step.

any help will be greatfull
