[mesa-users] How to Querry for initial abundances?

[Aaron Dotter]

Hi Ehsan,

At the start of a run, the composition adjustments are done in

subroutine do_star_job_controls_after

Which lives in star/job/ run_star_support.f.  The next extras routine to be
called after this, but before the evolution starts, is extras_startup.

My suggestion is to access s% xa(:,k) from extras_startup.  Any k should
work so long as you have a uniform composition.  You can define your own
initial xa array in run_star_extras that can be used later in your routines.
