It covers function learning and operator learning tasks and includes 15 types of PDE problems across multiple scientific domains, including fluids, materials, finance, and electromagnetics.20 21The dataset consists of 10 PDEBench data files and 6 self-generated data files, totaling approximately 286.9 GB. It can be used for model sanity checks, training, evaluation, and comparisons across problems.22 23Paper: [PDENNEval: A Comprehensive Evaluation of Neural Network Methods for Solving PDEs](https://www.ijcai.org/proceedings/2024/573)24 25## Supported Tasks26 27| Scenario | Description |28|---|---|29| PDE solution field prediction | Predict PDE solutions from equation parameters, coordinates, or initial conditions. |30| Function learning evaluation | Compare neural networks' ability to solve individual PDE problems. |31| Operator learning evaluation | Evaluate model generalization across different input conditions and equation tasks. |32| Cross-domain scientific computing | Cover fluid, diffusion-reaction, materials, finance, and electromagnetics problems. |33 34## Dataset Format and Structure35 36All data files are stored in HDF5 format with the `.hdf5` or `.h5` extension:37 38```text39data/40  PDEBench data files41  Self-generated PDE data files42```43 44The data includes coordinates, time, coefficient fields, boundary conditions, and solution fields for one-, two-, and three-dimensional PDEs. It covers problems such as Advection, Burgers, Diffusion-Reaction, Darcy Flow, Shallow Water, Allen-Cahn, Cahn-Hilliard, Navier-Stokes, Euler, Maxwell, and Black-Scholes-Barenblatt.45 46Fields and tensor shapes vary across PDEs.
