Hi John, This may be related: https://bitbucket.org/yt_analysis/yt/issue/765/gas-dark_matter_density-fails... The issue might also be fixed in unitrefactor. -Nathan On Wed, Feb 12, 2014 at 12:04 PM, John Wise <jwise@physics.gatech.edu> wrote:
Hi everyone,
I've run into the problem where yt-3.0 cannot generate deposited fields in Enzo datasets. For example, when I'm trying to access either 'dm_density', ['deposit', 'all_density'], or ['cic_particle_velocity_x'] in a single grid with the following lines
pf = load(sys.argv[-1]) g = pf.h.grids[0] dm = g['dm_density']
It crashes with the following error,
yt.utilities.exceptions.YTCouldNotGenerateField: Could field '('all', 'particle_position_x')' in output_0000 could not be generated.
even though it's in the dataset, and executing g['all', 'particle_position_x'] gives no errors. It looks like _generate_particle_field() is returning None, and I have no idea why since I'm not very familiar with the new field objects in 3.0.
Does anyone know what's going on?
Thanks, John
