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

[O Toloza]

Hi Pablo,

thanks a lot for the help. It does work.

I just give to it the value N which I read from the history.data
(lg_mtransfer_rate),

b% mtransfer_rate_old = N
b% mtransfer_rate = N*1.01

However it seems that b% s_donor% mstar_dot is stored, because I can
retrieve it within extras_binary_finish_step, but not within
extras_binary_startup.

I am trying,

b% mtransfer_rate_old =  b% s_donor% mstar_dot_old
b% mtransfer_rate =  b% s_donor% mstar_dot

Is there a way to know what are the parameters contained in a model?


Cheers,
Odette.
