Hi,


i simulated the flow through a heat exchanger geometry as you can see in the attached picture. Now, I want to analyse the vorticity in the area behind the heat exchanger with Paraview v5.8.1. I created a slice on which I wanted to calculate the average of the vorticity magnitude.

When I divide the result vort_magn = 0.1, caluculated with the filter "Integrate variables", by the area of my slice I get

vort_magn=30.86 1/s (Area = 0.045m*0.072m).

But when I check the line plot within this slice, it becomes clear that my averaged value should be higher!
Can anybody tell me, what is wrong in my calculation or what else I have to consider?


Thanks in Advance.
