[mesa-users] Inlist issue

[Frank Timmes]

the inlist contains at least one error:


>       am_D_mix_factor = 1d0/30d0


you need to enter this value as a decimal, am_D_mix_factor = 0.03333


>          photostep = 20

is an obsolete parameter in recent versions of mesa. use photo_interval = 50.

the inlist ran fine in 9793 after making these changes.

in future, please include any error messages emitted when reporting an issue.
