[Mesa-users] Li depletion due to thermohaline mixing

[Debasish Dutta]

Sir,
I am getting a plot like this

I am expecting something like this: (from a paper by Josiah Schwab)

As can be seen, there are two Li dilution episodes, whereas I am unable to
get the second dip, after invoking thermohaline mixing. I would be thankful
if you could suggest where I am going wrong.

Thanks,
Debasish
