[Mesa-users] Mass loss equations for different periods

[Aaron Dotter]

Hi Rodrigo,

You didn't say so but I suppose you already have an "other_wind"
implementation.  You can access anything in the star_info pointer from
within your other_wind routine, see here for details on how to do this.

http://mesa.sourceforge.net/run_star_extras.html

This would allow you to create a test to determine whether the star is
before or after the RGB bump.  Once you have that test, you can use it to
switch between two different winds.  E.g., inside an "if -else" block.

Cheers,
Aaron
