[Mesa-users] Problem with atm_T_tau_opacity at the helium flash stage

[Dreau Guillaume]

Dear MESA users,

With regard to a previous thread, we found that there is an issue with the option atm_T_tau_opacity  = 'varying' at the helium flash stage in the standard 1M_pre_ms_to_wd case. If we keep the same inlists as in the standard 1M_pre_ms_to_wd case, except atm_T_tau_opacity that we choose as 'varying' (default is 'fixed'), we see that the timestep becomes very small at the helium flash stage and the model cannot pass the flash.

Cheers,
Guillaume
