# Short Description |
|
|
|
Based on the compressible Euler equations, this dataset contains trajectories starting from multiple curved Riemann problems, 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 |

|
# 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-CRP.nc |
|
``` |
