[mesa-users] Zero Brunt-Vaisala freq. in outer regions of GYRE output files

[Richard Townsend]

Thanks!

I was hoping that adding an atmosphere would fix that — but from Josiah’s post, it seems it won’t.

Is there a good reason why the Brunt can’t be calculated in the atmosphere? Since the acoustic cutoff frequency depends on the Brunt, this issue is quite important.

cheers,

Rich
