Hi Matt,
I already sent an email which has the subject “About YT Divergence and Vorticity Plots from Jia-hung” to your gmail account.
In the email, it includes my data and my several frontend files.
Any suggestion is welcome and thank you in advance for the help.
Sincerely,
-Jia-Hung

Hi Jia-Hung,
Interesting. With cell-centered data, it ought to produce correct results.
Would you be able to send me a small sample dataset (off-list) and I
can take a look? Or feel free to stop by our hangout at 11AM Eastern
and I can try it out there.
-Matt
