[mesa-users] An error with rotation initialization

[Ehsan Moravveji]

Ok, let me respond to myself, as I figured out the issue.
The starting kick of rotation better be close to the ZAMS. So, mesa is not
really happy when it wants to contract a cloud
(create_pre_main_sequence_model = .true.) and at the same time rotate it.
So, the best option is to postpone it as late as the star reaches a more
stable configuration. I do it through the run_star_extras, when the model
reaches ZAMS.
So, just wrote it for those who might be possibly interested.

Best to all.
Ehsan.
