The meta-model is based on high order derivatives of geometric and flow variables (Turb’OptyTM solver) obtained by automatic differentiation of RANS solver. These parameters derivatives are stored in a continuous database. High order reconstruction leads to a drastic reduction in the number of design iterations. Industrial applications are presented.
