[mesa-users] The boundary of convection core in He-burning sdB phase

[军军 郭]

Hi all,

When calculating a sdB model, I found the convection core boundary is anomalous. The radiative temperature gradient (gradr) is  bigger 
than the adiabatic temperature gradient (grada)  with a difference about 0.02 in the convection core boundary which makes the
He-burning convection core smaller and  the evolution timescale shorter obviously comparing to the results of literature. I want to know 
how to make the  radiative temperature gradient  equal exactly to the  adiabatic temperature gradient at  convection boundary.
