Dear Nathan, Thank you for the answer, and links to the right page of documentation! They are very helpful to me. I'm going to try a particle filter. Y.T. 2017-10-11 16:24 GMT-04:00 Nathan Goldbaum <nathan12343@gmail.com>:
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# filtering-particle-fields) and then use the new particle type defined by the filter to create a deposited particle field ( http://yt-project.org/doc/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 ;)

Yes, it's Enzo data.

What simulation code are you working with? From the field names it sounds like Enzo data.

Dear yt-users,
Hi, I'm a new user of yt. 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. _______________________________________________ yt-users mailing list yt-users@lists.spacepope.org http://lists.spacepope.org/listinfo.cgi/yt-users-spacepope.org
