| # Short Description |
|
|
| Based on the compressible Euler equations, this dataset contains trajectories starting from 4-quadrant Riemann problems with uncertain interfaces, see https://arxiv.org/abs/2405.19101. |
|
|
| # Dimensions |
|
|
| The assembled NetCDF file has a **single** variable called *data* with dimensionality |
| - 10000 (number of trajectories) |
| - 21 (time steps) |
| - 5 (density, horizontal velocity, vertical velocity, pressure, energy) |
| - 128 (x-dim) |
| - 128 (y-dim) |
|
|
| It was simulated on the unit square up to T=1 and saved as uniformly spaced in space and time. |
|
|
| # Train/Val/Test-split |
|
|
| 9640/120/240 trajectories |
|
|
| # Download & Assembly |
|
|
| The dataset can be downloaded, e.g., via `huggingface-cli download`. |
|
|
| After download, the chunked data can be assembled into a single NetCDF file using the provided `assemble_data.py` script. |
| Use it as follows: |
| ```bash |
| python assemble_data.py --input_dir . --output_file CE-RPUI.nc |
| ``` |
