[mesa-users] a model that just stops running without warning

[Bill Paxton]

Hi Jieun,

The last release got out with a debugging test still enabled -- sorry.
It is fixed in version 4882 if you'd like to jump ahead (it has passed the full test suite).

-Bill

btw: it was complaining about calling the eos with logPgas ~ -71 and logT ~ 74  ----- no wonder it was unhappy!

When I tried running it with a different boundary condition (photosphere_tables), it initially converges and starts running fine but just stops in the middle of the run with no error messages. The terminal output doesn't say that the run was stopping due to a convergence issue or that the model finished running (in fact, the central temperature does not reach the stopping limit). I don't see why changing the boundary condition should lead to this problem since if there's a problem with photosphere_tables, it should just fall back onto the simple_photosphere BC by default (which_atm_off_table_option).
