Wow, this is amazing. Well done, Corentin! On Jul 16, 2025 at 10:57:34 AM, Matthew Turk via yt-dev <yt-dev@python.org> wrote:
Hi folks,
I wanted to highlight this PR that Corentin Cadiou just issued:
https://github.com/yt-project/yt/pull/5208
I love love love this syntax for adding new derived fields. Here's his example:
--- ds = yt.load(...)
ds.fields.gas.density_square = ds.fields.gas.density * ds.fields.gas.density ds.add_field(("gas", "double_density"), ds.fields.gas.density * 2)
ds.r["gas", "density_square"] ds.r["gas", "double_density"] ---
Check out the way he's using ds.fields.gas.density for input *and* he's assigning to ds.fields.gas.density_square. This is so much more user friendly.
Corentin implemented this after the presentations at the Higgs workshop about defining derived fields.
Even if we workshop this, fiddle around, whatever, I think this is a great concept that will be good for users both new and experienced!
