Standard velocity visualisation output for paraview give results in full vectors (arrows) and separated in x,y,z-directions. However, regarding a spherical set-up (eg. spherical shell, chunk or sphere) I would like to visualise the velocity field also in separate radial and tangential velocities.
I was wondering if someone already has written a postprocessor that creates vtu-files containing these spherical velocities and is willing to share it?
Or if anyone could give me a heads-up regarding an existing postprocessor which I could try to modify to make it myself and, of course, any tips in how to do so.
Thanks in advance,
