[Mesa-users] A question about rotational mixing for binary models

[Yamaguchi, Natsuko]

Hello,


I am a graduate student trying to test the effect of rotational mixing on some binary models and am having some difficulty.

I have only recently started using MESA and any assistance on this would be greatly appreciated.


Problem: Including rotational mixing makes no difference to the output so I believe it may not be turning on at all.


A few options I have set in inlist_project:

  *   evolve_both_stars = .false.
  *   m1 = 1.5d0
  *   m2 = 0.7d0
  *   initial_period_in_days = 0.75d0 (I have also tried this with m1 = 1.0, initial_period = 3.1)

A few options in inlist_1, including those of rotational mixing:

  *   set_uniform_initial_composition = .true. + initial_h1, initial_h2 etc. (I include this here because when I tried including mixing without this once, it did turn on - though there were still issues such as the value of the am_D_mix_factor not having any effect)
  *   am_D_mix_factor = 1/30d0
  *   D_ES_factor = 1 (I have also tried this with am_D_mix_factor = 1, D_ST_factor = 1 instead of D_ES_factor, etc.)

Am I missing anything in the settings for rotational mixing? If additional information is helpful, please let me know.


Thank you very much in advance,


Best,

Yamaguchi
