[Mesa-users] Star not evolving past CHeB phase

Hi João,

Could you try to use
convergence_ignore_equL_residuals = .true.
and 
use_Ledoux_criterion = .false.

This helped me pass the helium flash in the past for some difficult cases.

Anne

However, I tried lowering this limit and this still happens. Does anyone know what could be causing this? I've used the same inlists for stars with different masses and didn't encounter this problem.
