[Mesa-users] Select envelope zones only in a model

[Matheus Bernini]

Oops, I'm sorry I wasn't clear.

What I really I want is to multiply the Mdot by a factor of 2 when any cell
of the envelope reaches super-eddington luminosity. So, I need to evaluate
this condition during runtime. I would implement this in the other_wind
hook.

Cheers
