OK,I'll remember to keep conversations inside the mesa-users list!
When I follow your advise to add "use_other_torque = .true.", it's OK!
Thank you very much for your help again!

Jia, the older version of the synch related stuff was missing the very important control "use_other_torque = .true.". without that bit, the other_torque routines are not called for the star. Please try again adding that to your inlist.


Cheers!

Dear Pablo Marchant:
Thank you very for your help!
Here is my inlists and zams_filename = 'POPII.data',
and my version_number is 4942, thank you!

Jia, could you please share your sources, inlists and mesa version to test?


Cheers

Dear all,
When to evolve a LMXB system as rlo in test_suite, 
to instantaneous synchronisation between spin and orbit,
I set the &star_job as below:
&star_job
      new_rotation_flag = .true.



      change_rotation_flag = .true.
         new_omega = 2D-5 ! rad/sec
         set_omega = .true.
         set_initial_omega = .true.
         new_omega_div_omega_crit = 0
         set_omega_div_omega_crit = .false.



         set_initial_omega_div_omega_crit = .false.
         set_surface_rotation_v = .false.
         set_initial_surface_rotation_v = .false.
/ ! end of star_job namelist
and set s% other_torque => synch_spin_orbit_torque in subroutine extras_controls, 



isb=2 (in subroutine synch_spin_orbit_torque) for instantaneous synchronization, 
but the spin do not synchronizewith the orbital period, why?
And could set the star to be a rigid body with a uniform spin at different radius and synchronization with the orbital period?



Thank you very much!
Sincerely,
Jia Kun
