[Mesa-users] The problem of running make_pre_ccsn_llp

[Rob Farmer]

Hi,

>retry:logT>hydro_mtx_max_allowed_logT

Its telling you mesa is having problems with both the surface
(retry:get_T_tau -- L<==0) and the core
(retry:logT>hydro_mtx_max_allowed_logT) and is not unexpected for massive
stars evolving to core collapse.

>max model steps(10000)

You can change the maximum number of steps mesa takes by changing the
max_model_number. Note that the number of steps (10000)  is there to help
us when testing MESA and to stop MESA from running forever. If you have
changed the inlists then MESA may need more steps.

Plots also help (try a kippenhan plot) to see if the evolution is
proceeding or if MESA is having numerical problems. Also showing your
inlists helps so we can see what you have changed.
