[yt-users] code units

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.
