Re: [mesa-users] Fwd: Wind loss in MESA

[Alessandro P. <pa...@st...>]

Hi Rob,

my inlist files don't have the .txt extension, I guess that was appended 
by the mail server upon forwarding.

Anyway, the problem is now solved, indeed I had to specify the wind 
scheme prescription in the &control.

Thanks for your help!
