RealPDEBench RealPDEBench is a benchmark of paired real world measurements and matched numerical simulations for complex physical systems. It is designed for spatiotemporal forecasting and sim to real transfer evaluation on real data . This Hub repository ( AI4Science WestlakeU/RealPDEBench ) is the release repo for RealPDEBench. Website & documentation : realpdebench.github.io Raw HDF5 distribution : realpdebench.westlake.edu.cn Benchmark codebase : AI4Science WestlakeU/RealPDEBench Figure 1. RealPDEBench provides paired real world measurements and matched numerical simulations for sim to real evaluation. What makes RealPDEBench different? Paired real + simulated data : each scenario provides experimental measurements and corresponding CFD/LES simulations. Real world evaluation : models are evaluated on real trajectories to quantify the sim to real gap. Multi modal mismatch : simulations include additional unmeasured modalities (e.g., pressure, species fields), enabling modality masking and transfer strategies. Data sources (high level) Fluid systems ( cylinder , controlled cylinder , fsi , foil ): Real : Particle Image Velocimetry (PIV) in a circulating water tunnel Sim : CFD (2D…
