Fig. 11From: Enhancing CFD predictions in shape design problems by model and parameter space reductionThe relative error of the approximated outputs at different times. The relative error is computed on 100 test samples, using the high-fidelity lift coefficient to train the regression for \(t \le 20~\hbox {s}\), while for \(t > 20~\hbox {s}\) the DMD forecasted states are used for the trainingBack to article page
