[Mesa-users] Modify radiative temperature gradient "gradr"

[Yixiao Zhou]

Dear MESA users,


I'm looking for a method to adjust the "gradr" value in every step:

gradr_new = gradr_MESA * f_corr,

where the "correction function" f_corr depends on radius.


This modification should be done before MESA enters into MLT section so that I can determine convective boundaries and other convective-related quantities using the new gradr data:

Step (i) begin ... --> MESA calculate gradr --> modify gradr --> use the new value for MLT part --> ... step (i) end goto step (i+1)


I am wondering if there is a way to achieve this without changing the source code? For example, can this be done in run_star_extras.f?


Many thanks in advance,
