Dear professer

Thank you for your help!
The system I run is fedora-64, and the inlist files is in the annex.
by the way, if we set new_surface_rotation_v = 200, the mass transfer make star2 have the V_crit
 in the binary evolution, then the evolution will stop and the terminal will display as 
"stopping because of convergence problemsdt<min_timestep_limit". 
At this point, how to set the parameters that make the evolution keep runing? 
secondly,for the rotation binary star, what can I do that make timestep not too small?
Thank you!

Wang, for us to help you need to provide more detailed information. What system are you trying to run? At what point is it failing? You also need to provide the inlist files you used.

hi !
I'm run binary evolution in MESA-r8118. The cause of the given after the stop:

But I do not analyze it stop reason, so you can help me?
