Hello every one MESA users:
     I want to know how does MESA handle the convergent problem on He flash process. I had used other star evolution code and it stops on He flash, because the extreme increasing in Helium burning energy leads to a convergent problem: The finite-difference method is not convergent here, and Taylor's series expansion is not applicable to this kind of extreme change.  So i want to know which kind of numerical solution using in MESA that can prevent this convergent problem?
