Hi Aaron,

Thanks for the answer.

Yes, I can provide information. I attach the inlist of my model. I also attach a plot of Li7 versus radius, with the convective part highlighted in purple, where it can be seen that the LI7 abundance is not constant in the core. I did rapid calculations, which indicate that the timescale for lithium burning is around 4 minutes in the center while the convective mixing timescale should be around 4 days (if I didn't make mistakes).

Cheers,

Sebastien.
