Yes. It is hard to explain with text. You can find simple data (only one time step) and state file created in PV 5.4.1 (1.2 GB).
I just want to create a streamlines of vorticity field that uses programmable source as a starting point. At the end, I could manage to get some results.
In this case, the centroid is calculated by IntegrateVariable but it might be calculated also spicy or just regular mean. The programmable source is creating create circular source in the bottom of the shape cerated by Contour filter.
When I load and run the pipeline, I am also getting following errors but I could get some results. Do you think that they are related with Programmable source or any bug in 5.4.1.
Thanks for your kindly help,
Regards,
