[mesa-users] hydro_failed_to_converge

[Jaime Villaseñor]

Hi Bill, thanks for your comments.
I think that is the thing, and is what Pablo was just saying too, the test
went too far in the evolution. I haven't tried removing  the
max_number_backups line yet, because what worries me most is how the data
is looking. I'm sharing with you a plot of the donor mass vs orbital period
that I made with the old rlo test (from version 4909) and what I'm getting
with the binary_donor_only_implicit_mdot and the binary_donor_only tests.
What do you think is happening? Should I adjust something related to the
angular momentum loss? The third graphic is a completely impossible
scenario, so clearly I'm doing something wrong here.

Best, Jaime
