OK, in that case I wouldn't try to infer the stellar mass from the Dark_Matter_Density field (which does include stellar mass despite the name), instead I would define a particle filter for stars (http://yt-project.org/doc/analyzing/filtering.html# ) and then use the new particle type defined by the filter to create a deposited particle field (http://yt-project.org/doc/filtering-particle-fields analyzing/fields.html# ).deposited-particle-fields There's an example in the docs for how to do this with Tipsy data here: http://yt-project.org/doc/cookbook/constructing_data_ objects.html#creating- particle-filters For Enzo, you should use the particle_type field to create the filter - star particles in Enzo have particle_type equal to 2. Here's a short worked example:Hope that helps! And I hope to hear more from you - your name is particularly well suited to the yt project ;)-NathanOn Wed, Oct 11, 2017 at 12:58 PM, ｔyuta <y0u1t1a5.t@gmail.com> wrote:Yes, it's Enzo data.2017-10-11 10:17 GMT-04:00 Nathan Goldbaum <nathan12343@gmail.com>:What simulation code are you working with?

I have a question about the default 'Density' field and 'Dark_Matter_Density' field. Do they contain stellar mass? If so, how can I read and subtract stellar mass from the data?Sincerely,Y.T._________________
