Hello,

I am writing about a problem I am encountering in ParaView regarding the possibility of performing an azimuthal averaging, on a specific plane, of fluid-dynamic quantities at constant radius (for a sample of 100 radius) in my post-processing setup.  
The final goal is that I want to plot those averaged quantities as a function of the radius.

I already created isolines at constant radius in my geometry with “Contours”, but I haven’t found a way to proceed.

I hope my instructions are clear and I appreciate any help you can provide.

If I understand correctly there is no such filter in ParaView, however with the isolines generated, you should be able to get individual average for each line using a statistics filter. Do that works for you ?
