Re: [mesa-users] Inlist issue

Hi Frank,

Thank you for responding.

Is it rotation that triggers an issue with the ZAMS flag?

I set up accretion on a pre-MS 3M_o core. I then choose the model closest
in mass to what I
am after and restart from the corresponding photo. I used this setup
numerous times before,
but this is the first time I attempt to include rotation.

I figured I don't want to include rotation in the pre-MS model, since I am
looking for a certain rate
on the ZAMS (which is shortly after the first model I restart from - the
model relaxes quickly).

Thank you,

Yevgeni.
