I am trying to run some ppisn/pisn models and reproduce some results of Farmer
et. al (2019)
I ran some models of 35, 40, 45,........,100 solar masses (mellaticlity 10-3).
However, I am facing convergence problems in the 70 solar mass model. I get
this error message

stopping because of convergence problems dt < min_timestep_limit
terminated evolution: convergence problems
termination code: min_timestep_limit

I am using mesa version r11532.

Thanks and regards

Debasish Dutta
