​Hi Michael, John, Nathan,​

​My strealines script can be see here:​

http://paste.yt-project.org/show/5767/

​Modifying the periodicity manually via

ds.periodicity = (True, True, True)

causes the script to appear to execute for a very long time. I have never seen it run to completion, even for a single streamline. Perhaps I am just impatient.

If I do not directly modify the periodicity, the output I have pasted here:


Any help is appreciated.

Best,
Mikhail​
