Popis: We have constructed a grid of 3D hydrodynamic simulations of deep convective and line-blanketed atmospheres. We have developed a new consistent method for computing and employing T(τ ) relations from these simulations, as surface boundary conditions for 1D stellar structure models. These 1D models have, in turn, had their mixing-length, α , calibrated against the averaged structure of each of the simulations. Both α and T (τ ) vary significantly with T eff and log g .
