[mesa-users] Compositional Brunt-Vaisalla Frequency

[Manos Chatzopoulos]

Dear mesa-users,

  I am trying to use the MESA-computed compositional Brunt-Vaisalla 
Frequency (N_mu^2) as a newly
defined variable in run_star_extras.f where I am writing my own code for 
an application. I know this
variable can be printed out by default using the profile_columns.list 
(named us brunt_N2_composition_term).
However, when I try to use it in my code, in run_star_extras.f as
s% brunt_N2_composition_term it is not recognized. I get the following 
error message:

-I/Applications/mesasdk/include -c ../src/run_star_extras.f
../src/run_star_extras.f:135.35:

      s% brunt_N2_composition_term(k))*ftr1 + &
                                    1
Error: 'brunt_n2_composition_term' at (1) is not a member of the 
'star_info' structure

  I do not get this error message for the total, standard Brunt-Vaisalla 
Frequency, N^2
(using s% brunt_N2(k)) so I wonder what am I missing? Is the 
compositional BV Frequency
actually defined in a different way, using a different variable?

Thanks,

Manos
