[yt-dev] Question about vorticity and divergence plots

[吳佳鴻]

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?

Hi Jia-Hung,



Are values stored as face-centered or cell-centered in your output?
