[Mesa-users] heating area is not convective

[宋仁]

Dear Josiah,




You idea could be correct, than you. I will do more tests with much high heating rate.




Best regards,

Ren

Hi Ren,

The inlist files, initial model, and run_star_extras file are sent to you.

This made it easy to run your model.  Here's a pgstar plot from step 180.



You can see eps_grav ~ -1e5 ergs/g/s over the region between the burning shell and the top of your heating.  Over the 0.1 Msun between the burning shell and your the bottom of your heating, that is eps * dm ~ -1e37 ergs/s ~ 1e4 Lsun, so by that point, the L from the interior has fallen quite a lot so that radiative diffusion is sufficient to do the transport.


Josiah
