[Mesa-users] mass transfer reset to zero when resuming a run using a saved model

[Pablo Marchant]

Hi Odette,

the value that is missing in the run with the loaded model is the mass
transfer rate stored in binary info, b% mtransfer_rate. In your run_binary
extras you should have access to the extras_binary_startup subroutine. Can
you try setting the value of b% mtransfer_rate (and b% mtransfer_rate_old)
in there?

Cheers
