[Mesa-users] Model a star in the HR diagram

[Gonçalo Andrade]

Dear all,



I am currently using MESA and I need to make a model of a star as close as possible to a given T_eff and log(L).


Up to this moment I have been trying to use the solar_calibration example in the test_suite and the example in the Astero folder that is available inside the star directory, but I have encountered two main problems:


1) I have tried to remove the oscillation computation, since I don't need it and it consumes time, by removing all the frequencies in the file "inlist_astero_search_controls" and by commenting the &mode sections in the gyre.in file but, once the models get close to the expected, it begins calculating the frequencies anyway.


2) Ignoring the frequencies problem, I have managed to make small physics changes I needed and the calibration by simplex still functions perfectly fine. However, the moment I change the target T_eff and log(L) and the starting mass, alpha, etc, the code runs but always says it could not find chi^2 in that run, and does not present the results in the output file.

I have even tried doing a single run with a given mass, alpha, etc, and copying the resulting parameters to the target in the "inlist_astero_search_controls" and I still get the same result.


Are there any useful commands I might be missing?

If needed I can attach the inlists I am using.



I grateful for any help you could give.


Best regards,

Gonçalo Andrade
