Re: [yt-users] yt-users Digest, Vol 78, Issue 38
Hi Matt, Those fields are not in my derived field list. That is ds.derived_field_list. Do I have to add them in some way? Or is there a way to check if yt didn't find the cooling??.dat files? Thanks, Ari On Thu, Aug 14, 2014 at 1:54 PM, <yt-users-request@lists.spacepope.org> wrote:

Hi,
Does anyone have code to create derived fields of ionization states, e.g. HI, for ramses data sets? If that's a no, does anyone have an example of a derived field where you have to read in a table and interpolate the field values.
Thanks,

Hi,
according to http://yt-project.org/docs/2.6/analyzing/creating_derived_fields.html?
what worked for me for enzo data is the following
def _HINeutralFraction(field, data): return data['HI_Density']/(data['HI_Density']+data['HII_Density'])
add_field('HINeutralFraction',function=_HINeutralFraction, units=r"\rho_\mathrm{HI}/\rho_\mathrm{H}")
unless there's something strange with ramses dataset, the above should work.
From G.S.

Hi Ari,
My reading of yt/frontends/ramses/fields.py is that this should be implemented already, using the cooling_%05i.dat files. If it's able to find those files, it will create the appropriate derived fields from them -- specifically, I think it can do Electron, HI, HII, HeI, HeII, and HeIII. Is it not creating those?

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 On Thu, Aug 14, 2014 at 1:56 PM, Professor Maller <amaller@citytech.cuny.edu> wrote:
