[Mesa-users] The problem of running make_pre_ccsn_llp

[Rob Farmer]

Hi
Please keep your replies on the mesa-users mailing list. I will not reply
to further messages sent off-list.

So the video is nice but remember a kippenhan diagram shows the evolution
of a star over time. So the final image is all you need to summarise the
evolution up to that point.

>So I  stop running the model because the model has exceeded the max
model(10000)  before.

Your model is stopping during core helium burning. But it looks like it's
still evolving (note the changes in the location of the convection zone). I
would suggest just removing the maximum model number limit, it is not a
physical limit and your model is still evolving so it's possible that  if
you let it evolve further it will leave the core helium burning phase.
