[Mesa-users] Question about [Fe/H] in solar calibration

[Aldo Serenelli]

Hi,

could it be you are using the initial values you get for Z and X to 
obtain the 0.04. Given there's grav. settling in the model, the initial 
value should be larger (about that amount), compared to present day 
value, which is in fact the one used for the calibration (and is by 
definition 0).

Hope this helps,

Aldo
