+This dataset contains the raw (before interpolation) data of the CFDBench dataset, from the paper [CFDBench: A Large-Scale Benchmark for Machine Learning Methods in Fluid Dynamics](https://arxiv.org/abs/2310.05963), which is used for training and evaluating data-driven neural operators for fluid dynamics. This dataset is very large and likely not needed if you just want to evaluate and/or train a data-driven neural operator.
