[Mesa-users] astero grid

[Bruno Lustosa]

*Dear MESA developers and users,*

I am trying to perform an asteroseismology grid search using MESA version
r24.08.1. My goal is to evolve a star to a specific giant branch phase and
then trigger a grid search to find the best-fitting model for a set of
observed frequencies.

The problem I am facing is that while the stellar evolution runs perfectly
and stops at my specified condition (using a sequence of 1 to 4 stops), the
subsequent asteroseismology search phase is not initiated. The run simply
terminates after saving the final model, and the PGSTAR plots for 'astero'
(Echelle, χ2, etc.) never appear.

I have already checked the following configurations, based on the
documentation:

   -

   My inlist_project contains the &astero namelist with do_astero_search_op
   = 'grid'.
   -

   The astero_search_controls_inlist_name parameter correctly points to my
   inlist_astero_search_controls file.
   -

   My inlist_astero_search_controls uses the modern grid definition
syntax (grid_type
   = 'uniform', along with the uniform_grid_... parameters for age, Z, and
   alpha_mlt). The older, deprecated search_*_param flags are not being
   used.
   -

   My frequency data file (freqs.dat) has been checked for duplicates and
   is correctly formatted (l, nu, nu_err).

My questions are: Is there any other configuration, flag, or known issue
that might prevent the transition from the evolution phase to the search
phase after a clean stop? Could the type of stopping condition be
interfering with the 'astero' trigger? And why do no plots appear, even
when astero_pgstar_controls is specified?

I am attaching my main inlist, inlist_project, and
inlist_astero_search_controls for your review.

Thank you very much for any help or suggestion.

Sincerely,

Bruno
