[Mesa-users] [mesa-users] Beyond the Hertzprung gap - Solar metallicity - Massive stars

[Amedeo Romagnolo]

Hi all,

I have been struggling recently with evolving massive stars at solar
metallicity beyond HG. As you can see below, my star (53 Msun at ZAMS) is
stuck at what I deem to be the end of its HG phase (don't mind the
incorrect labels on the HR diagram).

I cannot wrap my head on what the problem is, since if I go to Mzams<52
Msun I can easily go into the giant phase.

It always stops due to timestep limit. Inlist attached.

Thanks in advance for any help,

Amedeo Romagnolo
