[mesa-users] convergence problem

[Ehsan Moravveji]

Hello MESA users,
I get this convergence error when setting create_pre_main_sequence_model
to true. Does anybody have an experience unscrewing this sort of issues?

Turning off the create_pre_main_sequence_model will solve my problem, but
this is not what i want. The inlist is attached.
I am at version 4589 (the latest+SKD), and run with over 12 nodes on a
64bit Linux cluster.
Thanks for your concern.

Ehsan.
