Does anyone know how to calculate line integrals in FLUENT? I am doing a 3D unsteady simulations and would like to calculate the line integrals of several self-generated lines. I am aware there is one option in Report>Surface Integrals>Line-surfs. I tried to get the line integrals of velocity magnitude via this option but it returned zero values. I was confused cause the velocity magnitude along the lines that I defined are not zero but why the line integral is zero? Could anyone give me some suggestions? Thank you....

you can define surface and do integration over it
but about line i,m not sure that u can do it in 3d models.
use Matlab to over come this problem.export to Matlab and do it
