[Mesa-users] Problem with 20Msun star and z=0.005 : Fe-core is not producing ?

[Rupak Roy]

Dear Mesa users,

I am trying to run MESA with 20Msun, Vrot=200kms-1, and z=0.005 to Fe-core
infall >1000kms-1, without including any mass-loss, or overshooting.
However, the run goes up to Si-burning stage and doesn't seem to progress
from there. The Mesa inlist file is given below. Can you please let me know
why Fe-core is not producing ? Any suggestion, how to proceed .....

This is my inlist

&star_job



!LOAD from ZAMS model


load_saved_model = .true.

saved_model_name = '20msun.mod'


set_initial_age = .true.

initial_age = 0 ! in years


set_initial_model_number = .true.

initial_model_number = 0


set_initial_dt = .true.

years_for_initial_dt = 10



! rotation


change_rotation_flag = .true.

new_rotation_flag = .true.

new_surface_rotation_v = 200.0 ! km/sec

set_surface_rotation_v = .true.


change_v_flag = .true.

new_v_flag = .true.

center_ye_limit_for_v_flag = 0.45d0


auto_extend_net = .true.


/ ! end of star_job namelist

!*----------------------------------------------------------
------------------


&controls



      initial_mass = 20


! opacity


     initial_z = 0.005d0

     use_Type2_opacities= .true.

     Zbase = 0.005d0



fe_core_infall_limit = 1.0d8
