[mesa-users] Problem with the overshoot parameters

[Dennis Stello]

...and check the the defintions of the overshoot parameters in the 
different codes are the same (and tranform if they are not).

I compared the results with this codes and there is a huge difference. The overshoot effect is much higher in MESA as compared to the other codes. I think there is some problem with the overshoot implementation
