Hi All

I am using the last mesa version with the last sdk version.

I am evolving a system with M1= 2Msun with M2 = 1.2Msun with a period of
few days.

I changed the time step and add winds for the mass loss however the
metallicity is always set to 0.02. On star control default i found how to
change the initial_z but for a single star not a binary.

The same command does not work for a binary.
How i can change the metallicity for a binary star ?

Thanks for your support
