I trying to add the metallicity field back to the enzo frontend and am wondering what field registry it would be appropriate to put it in. Anyone have any thoughts on this?
Additionally, I noticed that the particle field metallicity_fraction currently has units of Zsun. As far as I know, this is not correct. I believe the field is actually unitless and would have to be divided by ~0.02 to be in units of Zsun. How can I set this up correctly to make it aware of these units?
Should I make a "code_metallicity" unit? This might actually be usable for the gas metallicity field as well.
