[Mesa-users] Minimum requirement for blue loops for supergiants

I've been trying to get blue loops for supergiant stars (13M and higher) by
starting from a preMS model and evolving. My inlist works perfectly for
lower mass stars but I don't see the loops for higher masses.
I know that these loops are very sensitive to things like overshooting so I
was wondering if anyone had an idea of what the minimum controls I need are
to see these loops?
I am using the default X and Y with initial Z=0.0006. At the moment, I am
just turning the Ledoux criterion on and setting alpha_semiconvection=0.1.
I tried several different mixing lengths and overshoot fractions (in the
range 0.01 to 0.1) but so far I see nothing.
I'd be very grateful for any help you can give.
