calculate flow rate through a selected section? - paraview
 

Dear OpenFOAMers,

I completed a pimpleFoam case. I would like to calcuate flow rate through a "selected" cross-section in paraview. Is it possible?

In paraview, after I extracted the cross section I wanted, I tried to use the Calculator function. I saw the U vector, but, I do not see A so that I can do a U dot A to get flow rate.

Can someone point to me a dirction?

I am using OpenFOAM-2.1.x with paraview-3.12 on OpneSUSE 12.1.

thanks!
