[mesa-users] Modify criterion for onset of convection

[Ireland, Lewis]

Hello,

I wish to modify the Schwarzschild criterion for the onset of convection, i.e. nabla > nabla_ad, by replacing it with, nabla > nabla_ad + delta, where delta can be user inputted constant, thus affecting the superadiabatic profile of the model. I was following tutorials from the MESA summer school 2014, covering how to modify the standard convection prescription both inside and outside mlt_eval(), but I’m not sure that these can help me with the modifications I wish to make, as the tutorials stop before covering how to implement your own prescription of MLT.

I know it should be analogous to how your implementation of Ledoux criterion works, but it isn’t clear yet how to go about this. I have attached my run_star_extras.f, which as it stands includes other_mlt() (renamed to my_other_mlt()), mlt_eval() and do_mlt_eval().

Thank you,

Lewis
