[Mesa-users] Differences between MESA r10398 and 25.12.1 for rotating very massive stars

[Natalija M]

Dear MESA users,

I am currently trying to switch from r10398 to 25.12.1, and while doing so
I noticed some differences in the results.

I evolved rotating very massive stars with low metallicity using the
inlists attached below (which are quite similar for both versions). For
solar metallicity, the results are in very good agreement between the two
versions. However, for lower metallicities, the models evolve very
differently, as illustrated in the HR diagram. I am not sure what in the
older version leads to this behavior.

I would greatly appreciate any help or guidance.

Best regards,
Natalija Mladenović
