The appearance of the pathlines changes within one iteration in a case that should be converged. Moreover the number of aborted lines changes:

at it 1000: number tracked = 1215, aborted = 240, incomplete = 2
at it 1001: number tracked = 1215, aborted = 279, incomplete = 2

I repeat it: judging from the appearance, the pathlines aborted are the totality of them and not “only” 20%~30%.

Thank you for following my case Rob. Please let me know if it results in a bug.

Edit: sorry, I replied to the thread without noticing your edit. So can you confirm that the issue is present also in the 2022 releases?
