[Mesa-users] inlist for ~2Ms star terminating on the TP-AGB, mesa v10398

Wed Sep 5 16:14:39 EDT 2018

grab my work directory or just the inlist from the 2018 mesa summer school.
it takes a 2.1 msun from zams to through all the thermal pulses to a wd.
i've also used it on many other masses.

http://cococubed.asu.edu/mesa_market/education.html

it is not minimal as i aim to publish something with it (paper I submitted).

I and some of my colleagues are experiencing the same behavior with other models that are known to go through extensive pulses, where it hangs on the second pulse. I'm just trying to check all the options. Thanks.
