[mesa-users] Termination codes

[Choi, Jieun]

Hi Hannah,

http://mesa.sourceforge.net/controls_defaults.html#when_to_stop lists the
different options for terminating your run. You can, of course, set your
own stopping criterion using run_star_extras.f.

However, the case you've brought up --- STOP debug1: do_kap_for_cell --- is
not like the other termination codes, such as the maximum number of models
or max age reached, because this appears to be an actual problem.

If I grep 'debug1' in mesa/star/private, I can see that the statement is
being printed from opacities.f90.

In the subroutine do_kap_for_cell, I see

         if (is_bad_num(s% opacity(k))) then
!$omp critical (star_kap_get)
            call show_stuff
            stop 'debug1: do_kap_for_cell'
!$omp end critical (star_kap_get)
         end if

So the opacity in one or more of your cells is likely a NaN. Without more
information on the models you're running, it's hard for me to tell what's
going on. Maybe others will have better insights!

There are so many of these STOP debug statements that it's hard to list
them all. Try grepping 'stop' in star/private to see just how many there
are!

Cheers,
Jieun
