[Mesa-users] Is it possible to add a parameter to star.data.inc in order to use it in a computation in the run.star.extras?

[aldanag at campus.technion.ac.il]

Hello,


 I am trying to inject energy to a star via the"run_star_extras", and the subroutine I use has access


to the srar_info pointer, so I can use only the quantites that are defined in star/public/star_data.inc to make the energy computations.


However, one of the paramaters I need to use- avg_charge_H (which I can see at the output of the profiles) is not defined in


star.data.inc in any way.


 I found that this parameter is from the ionization module, and when it is passed to the star module via:

 get_ion_info(ion_iZ_H,k), this is from:   star/private/profile_getval.f90  that contains the lines

            case (p_avg_charge_H)
               val = get_ion_info(ion_iZ_H,k)

yet p_avg_charge_H also isn't defined in star.data.inc. I tried to add it manually and the runs still doesn't compile.

My question is: Is it possible to add a parameter that exists in MESA to the star.data.inc, and if it is possible what is the right way to do that?

Thanks in advance,

Aldana.
