1st question -- does your project really require going to iron core, or would it be enough to go to within
a few years of iron core so you could terminate at an earlier burning stage such as Neon?
If so, you'll have a much easier time and can look at a wider range of masses without great difficulty.
If you need to go to core collapse, the mass range 15 to 25 seems to be a "sweet spot" where the
computation doesn't have too much trouble. There are experts (some on mesa-users) who can
do more, but I'm not one of them.
You might want to run the star/test_suite/15M_si_burn case to see an example go to iron core infall.
