There is a filter in ParaView named Vortex Cores. All filters in ParaView have a corresponding Python function of the same name.
It sounds like you are jumping into the ParaView scripting very fast. I would recommend playing with the ParaView GUI first and trying the Start Trace / Stop Trace to demonstrate how to use these functions in the Python bindings.
Thank you for responding so quickly! I am using Paraview 5.6 (for reasons) and the reason why I went into the trying python scripting is because the Vortex Cores filter doesn’t show up in my filters list.
Any insights on what could be causing the omission ? Is there a plugin that I have to load before it shows up in the filters list ? or Should I upgrade to the laster version ?
Thank you so much! That pretty much answers my question. I had an inkling that it might just be feature not included in 5.6 but was hesitant to upgrade; Apologies for asking a trivial question.
