[yt-users] yt-users Digest, Vol 78, Issue 38

[Matthew Turk]

Hi Ari,

Looks to me like it may actually not be enabled by default for some
reason.  Can you try calling:

ds.field_info.create_cooling_fields("")

and seeing if that adds the correct fields?  If so, I'll update the
code to do this automatically.

-Matt
