PARTICLE_AGE NOT DEFINED FOR RAMSES DATA
Hi, I've recently started working with yt and am trying to extract "particle_age" for newly formed stars in my simulation:
def formed_star(pfilter, data):
filter = data["all", "particle_age"] < 0
return filter
add_particle_filter("formed_star", function=formed_star, filtered_type='all',
requires=["particle_age"])
However, I encounter an error:
the fields
('all', 'particle_age'),
required by the "formed_star" particle filter, are not defined for this dataset.
Could anyone please recommend a possible solution for why "particle_age" is not being detected for my dataset? Thanks.
Hi, Just a head's up, the gmail account you used to contact the mailing list isn't subscribed so I had to manually let it through. It may be the case that your dataset doesn't have the particle_age field defined, I think only a subset of RAMSES datasets have it defined. Can you tell us what ds.field_list is? Can you also tell us what yt version you are using? -Nathan On Sat, Mar 10, 2018 at 5:16 AM, Samhitha Vadlamani < vadlamani.bits@gmail.com> wrote:

This means you built yt from source. Do you know what changeset hash you used?

I see. One possible check I could do is to find out the units for these fields and hope for only one of them to have time units. Is there anything else I could do to confirm the field? I’m not really sure of what a change set hash is or if I could find out at this point? Would updating yt help in any way?

I’m sorry but I’m not familiar enough with the RAMSES output format to be able to confidently answer your questions. I’ve pinged Corentin Cadiou, who has been doing a lot of work recently to improve the RAMSES frontend in yt, hopefully he’ll have a better idea. The changeset hash is a way of identifying precisely which version of yt you have installed from the git repository. If you don’t know what that is that’s ok, I was just curious if you happened to have an old version installed. It’s possible installing the latest development version of yt might help things if you originally installed a version from last Fall, although if you installed yt recently you probably have a version reflecting the latest state of the RAMSES frontend.

Thank you for your efforts. I looked at those "extra" fields and none of them corresponds to time: they're all dimensionless. On Sat, Mar 10, 2018 at 10:32 PM, Nathan Goldbaum <nathan12343@gmail.com> wrote:
