[Mesa-users] ?==?utf-8?q? Timestep issue at the He flash stage

Fri Feb 5 17:57:05 UTC 2021

Hello Bill,

Ah yes, of course! Attached is the model saved right after the termination of inlist_to_start_he_core_flash that I sent earlier. It is approximately 100 steps before the timestep stopping condition. You can rerun it with inlist_to_end_core_he_burn, I send it to you in this email. I checked that I could reproduce the same problem from this starting model.

Have a good day!

Sincerely,
Guillaume

  i should have mentioned that you need to double check that you can start a run from the new saved model from ust before the problem and recreate the same (or similar) problem from that starting model.    you probably already thought of that, but i wanted to remind everyone of that important step! b  On Feb 5, 2021, at 8:20 AM, Bill Paxton <paxton at kitp.ucsb.edu> wrote: Hi Guillaume, I’ll take a look, but it would be a big help if you’d send a saved model from 100 steps or so before the trouble starts so I don’t have to redo the run up to that point.    Cheers,Bill  On Feb 5, 2021, at 5:44 AM, Dreau Guillaume <Guillaume.Dreau at obspm.fr> wrote: Dear MESA users,

I am glad to know how flexible MESA is to model stellar evolution up to the asymptotic giant branch! With the latest version of MESA (mesa-r15140), I aim at studying the structure differences between red giants and asymptotic giants. To this end, I started using the test suite case 1M_pre_ms_to_wd and I adjusted the inlists to take into account the micropĥysics and macrophysics adapted to my study. Attached are my inlists. I am facing an issue at the tip of the red giant branch. In my inlists, when I set atm_T_tau_opacity = 'varying' (default is ‘fixed’), the model is no longer able to pass the He flash stage. It seems that the timestep becomes too small, reaching min_timestep_limit that is the smallest timestep allowed before the run stops. I tried to decrease that timestep limit as much as possible, but it does not fix the issue. I also tried to play with the parameters atm_T_tau_errtol and atm_T_tau_max_steps,  but without success. Below are the messages I get that seem to be linked to the timestep stopping condition. Other surprising thing is that when I choose a lower mass (0.9 M_sun with the same other inputs),  I end up having the same issue but also with default option atm_T_tau_opacity = 'fixed'. Then, it does not seem to be exclusively due to the atmosphere inputs. It seems that the residuals are too high so that the timestep does not stop decreasing. I tried setting max_resid_jump_limit = 1d10 (default is 1d06), but it does not help to fix the issue.
Do you have an idea about how to fix this and how to pass the He flash?
I hope I didn’t forget anything to share with you.

Many thanks in advance!

Sincerely,
Guillaume
