[mesa-users] hydro_failed_to_converge

[Pablo Marchant]

Jaime, the new version saves binary output to binary_history.data in the
work directory, data is not appended anymore to the donor logs.

Could you send me your inlists on the new version? The inlist struxture now
is different so the previous one wont work for me to test what youre doing.

Also, what do you mean by strange donor mass?
