Setting Up Identical Fields
===========================

Because the codes involved in AGORA are so diverse and come from totally different origin points, they do not generally have the same field names. This can be incredibly challenging for a user to compare if, for example, their code uses ('gas','mass') and the other uses ('Gas','Mass') to denote the same thing. Some work has been put into standardization on the ``yt`` end as well, but we found it was much easier to set up new fields with standard names to make sure they were comparable (in some cases, like metallicity, the codes do not even record the same level of detail internally, and so using the internal fields can sometimes be problematic).

The basic fields of any simulation are density, temperature, and metallicity.
