[Mesa-users] Output Models at Specific Hydrogen Abundances

[Matteo Cantiello]

Hi Hiyaa,

You can achieve what you need by modifying the *run_star_extras.f90 *file
in your local *src* folder.
Please find details on how to do this here
https://docs.mesastar.org/en/latest/using_mesa/extending_mesa.html#choosing-when-to-output-history-or-profiles


The example provided is quite similar to what you need (saving a profile
when the central density reaches certain values). In your case you want to
identify the hydrogen central abundance. Maybe useful for you to look into
the source code for something like 'center_h1' and see how this is usually
determined in MESA…

Let us know how it goes!

Matteo
