[Mesa-users] crashes at Psurf=1 Ba

[Farag, Ebraheem]

Hello Sho,

I am not aware of such an issue., but from what you've shared, it could be a bug, but it could also be related to your model setup. Perhaps you can share a working clean directory with us and, maybe, we can find the source.

Dear EbF,

I see your point. The case with Tsurf=100 K was not good to show my problem.

I attached the log file of the first 1000 lines with Tsurf=300 K. In this case, the EOS should be in the domain. I don’t set up pgstar, so I cannot use "show_TRho_Profile_eos_regions = .true. “ for now. I will try it later.

In the new log file, MESA got the EOS error at line 180, but after several retries, MESA can proceed further. So this is not a big problem.

>From line 698, MESA retries again, and this is not related to the EOS error. Most problematic crashes do not relate to EOS errors. So I think EOS is not the main cause.

Do you know any modules that could relate to 1 Ba in MESA?
