Dear Paraview experts, I completed a CFD calculations which contains, U (velocity field) and p (pressure field). I used "extract selection" to select a cross section. I then would like to calculate the flow rate through this cross section, ie, U dot A. I tried to use the Calculator function. I saw U in the vector field. Is there a way to have A (area, vector field) so that I can do U dot A, then, integrate U dot A to have flow rate?
Thanks! Pei-Ying
