Averaging along a line on a boundary patch
I'm trying to get the average of a scalar field variable along specified lines on a boundary patch. The boundary patch is not completely planar, so the lines along which I want to sample would exit and re-enter the flow domain (boundary). I've tried using the sample utility, but for some reason it only picks up a segment of where the line and patch intersect. I can see from paraview that there is more than what sample returns.
Here's a sample of what I have in sampleDict:
If I can at least know how to sample values along a line I can do the averaging externally. Is there a simple way to do that? Is there something I'm doing wrong in sampleDict :confused:?
Any help or suggestions appreciated.
