[Mesa-users] hydro_newton_step_failed to accept

[Francis Timmes]

"hydro_newton_step failed" means that the solver could not find an acceptable solution.
avoiding his message, should it occur, depends on the model. hence request to send your inlist.

also, please keep mesa-users on all replies and 
please do not send screenshots when a cut & paste of plain ascii text will suffice.
