Convection in Massive Stars [Matteo Cantiello]

Please find below MESA Inlists for 60 Msun model at solar metallicity (showing envelope density inversion and envelope convection regions, including deep iron CZ). This is the model I've shown during my talk on convection. MESA version 9268 (install MESA from here)
