[yt-users] problem with fields that use ghost zones

[Britton Smith]

Hi Sam,

That fixed it, thanks!  I actually encountered this problem while working
on my own derived field that used ghost zones and was using
VorticitySquared as my example for how to do it.  I think in the past it
was not required to list the fields with ValidateSpatial, which is why it
was working as is in older versions.  I wasn't able to find documentation
on how to make fields that use ghost_zones.  If it's in there and I just
missed it, could someone point me toward it?  If not, I could add something
to the Creating Derived Fields section.
