Question about vorticity and divergence plots
Hi Matt, I am sorry that somehow my mailbox could not receive the mail successfully, so I copy and paste the previous discussion at the bottom of this email. I think my data is cell-centered, and I give YT my velocity field in the name of ["velx", "vely", "velz"]. Is there anything wrong?

Dear all,
I’m new to YT. I encountered a problem when trying to plot the
divergence and vorticity of a velocity field with an octree data
structure similar to FLASH.
I put a cylindrically symmetric velocity field into YT. So far I could
get Velocity Magnitude Plot correctly and the Velocity vector looks
also fine (see the attachment). However, the VorticityMagnitude and
DivV plots have a offset toward the top right corner. I was wondering where I did it wrong.
Any suggestion will be welcome, and thanks for the help in advance.
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 On Wed, Mar 5, 2014 at 1:31 PM, 吳佳鴻 <r00222055@ntu.edu.tw> wrote:
