[Mesa-users] PISN models for high metallicity

I can’t run 11701 or 12778 on my current machine, but i would suggest
looking at the surface regions of the trho profile to figure out if it it’s
just the surface going haywire, especially at higher metallicity. It’s good
to see what’s going on before the model crashes.
