I have a cuboidal domain where the flow is occuring. I want to compute the radial distribution of circulation at a particular slice (plane) taken from the cuboidal domain. So for calculating circulation, I need to choose multiple closed curves (circle in my case) to integrate the tangential component of velocity . My question is, how can I extract the velocity data along a circle from paraview. Is there any filter or tool to extract data along any closed curve in paraview ?
Thank you in advance
