Scheme for the multi-fidelity POD framework. The arrows indicate the relationship between the different methods. In the blue box the dashed arrows indicate the online phase when the input parameter is provided. In the purple box the dotted arrows indicate the information flow if only sensor data are provided. The central red frame emphasizes the computationally expensive offline phase
