[Mesa-users] Switching MESA-r9798 to the newest version r24.3.01

[Francis Timmes]

hi rita,

thanks for the plot - looks reasonable. i will repeat eb's suggestion to post your inlist(s) and any associated run_star_extras, otherwise its impossible to offer any suggestions for potentially improving the run time. in addition, please give the value of your OMP_NUM_THREADS environment variable.

It's nearly impossible to speculate otherwise except to say that the current version of MESA is much more careful  in a variety of respects and takes extra solver iterations to ensure good numerical convergence with respect to previous versions including the use energy conservation to maintain numerical accuracy (something not done in mesa-r9798). Much of this is documented in MESA IV <https://ui.adsabs.harvard.edu/abs/2018ApJS..234...34P/abstract> and MESA V <https://ui.adsabs.harvard.edu/abs/2019ApJS..243...10P/abstract>.

I spent 10 days for the new version to get 2 bursts but the old version I spent 3 days to get 5 bursts. All the input files are the same for both versions. Is there any way to speed up the new version? Thank you very much.

How do I change the newest version to use the same eos? I tried not to command anything in eos and it seems that it is using eos_free. How do I change the eos to helm_table.dat? Thank you very much.
