[mesa-users] 100 Ms fails to converge

All,

I am beginning to run mesa-star on massive stars.  Up to 50 solar masses,
everything seems fine.  When I try to run a 100 solar mass star, it fails
to converge toward the end of H burning and never makes the transition to
He burning.  I've tried a number of combination of finer grids, relaxed
convergence criteria, etc, but haven't found a combination that works.  Any
words of wisdom from more experienced users?

Thanks,
