Hi, Everyone--
I'm trying to get code units from enzo for a cosmology run, but in_units('code_density') seems to do nothing. 'code_mass/code_length**3' seems to work. Is this a bug, or a feature?
ad['density'].in_units('code_mass/code_length**3')
YTArray([ 0.9970247 , 0.99774731, 0.99854185, ..., 0.99993769, 0.99914176, 0.99841755]) code_mass/code_length**3
ad['density'].in_units('code_density')
YTArray([ 1.87321000e-29, 1.87456764e-29, 1.87606042e-29, ..., 1.87868293e-29, 1.87718755e-29, 1.87582689e-29]) code_density
Thanks! d.
Hi Dave,
It's neither a bug nor a feature; "density" is represented as a "code_mass / code_length**3" primitive.

Hi, Matt-
It's neither a bug nor a feature; "density" is represented as a "code_mass / code_length**3" primitive.
So what does code_density do?
Thanks a bunch! d.

This is supposed to be set to code_mass/code_length**3, but you've actually spotted an oversight in the way we set up units in the Enzo frontend such that Enzo units turn out subtly different from units in the other frontends.
I've gone ahead and issued a pull request to fix this:

Thanks a bunch! d.
