[Mesa-users] Strange error when running a MESA model (NaN values)

Hi Matheus,

I'm confused by your inlists and your terminal output.  The latter says
you're using the Eddington_grey atmostphere boundary condition but this
doesn't seem to be set in the inlists.  Do you know

Anyway, the error message in the terminal says that the Eddington_grey
atmosphere T-tau integration has failed.  You might have better luck using
the simple_photosphere from the start.

The atmosphere boundary condition is set in the &controls inlist.

Cheers,
Aaron
