In my run, the thermal pulses get started around model number 21000. I
killed the run at model number 107063, which is the point by which I
counted 34ish thermal pulses.
This isn't really my area: I seldom evolve models much past the RGB bump,
let alone beyond helium ignition. I don't know which of the extra
controls might be holding you up! That said, I'm not used to the rotation
controls but it looks to me like you're creating a 0.98 Msun star
and setting the rotation rate to 204.8 km/s. Is that not a bit quick? I
might be misinterpreting things.
