[Mesa-users] No He burning for tutorial M=0.81 star

[Richard Battistini]

Hello,

I am attempting to complete a simple task of using the inlists in the MESA
tutorial to run an evolution track for a star with initial mass = 0.81 all
the way into at least the asymptotic giant branch. I was expecting to see
the track move onto the horizontal branch stage in the pgstar HR diagram
and the corresponding helium burning in the Trho plot. However, there
seemed to be no evidence of the HB in either of the plots.

I was wondering what would be the fix here in order to see the star clearly
moving into the HB phase and He burning, and then eventually into the AGB?
I have attached my inlists below in order for one to reproduce the problem.
My operating system is Ubuntu 18.04.5 LTS, MESA version 15140, and MESA SDK
15140 released December 18 2020 (current). Any assistance would be greatly
appreciated.
