[Mesa-users] Fortran runtime error: Cannot match namelist object name overshoot_f_below_nonburn

[Pedro Nuno David Gomes]

Hello MESA users,

I'm a MSc student and I'm attempting to replicate some results for a red 
giant star model using MESA, from the following paper:

https://arxiv.org/abs/1602.03056 ("Asteroseismic signatures of evolving 
internal stellar magnetic fields")

Where the used inlist is on page 13. I started using MESA very recently 
so I'm still getting a bit acquainted with it. After compiling and 
running the code I obtain the following error:

Fortran runtime error: Cannot match namelist object name 
overshoot_f_below_nonburn

Why is this happening and how do I solve it? Here is the inlist I am 
using, very similar to the one in the paper,

Thank you very much.
