# Short Description |
|
|
|
Based on the compressible Euler equations with gravitation, this dataset contains trajectories of the Rayleigh-Taylor problem, see https://arxiv.org/abs/2405.19101. |
|
It also contains a passive tracer that is carried by the flow. |
|
|
|
# Dimensions |
|
|
|
The assembled NetCDF file has a **single** variable called *solution* with dimensionality |
|
- 1260 (number of trajectories) |
|
- 11 (time steps) |
|
- 6 (density, horizontal velocity, vertical velocity, pressure, passive tracer, gravitational potential) |
|
- 128 (x-dim) |
|
- 128 (y-dim) |
|
|
|
It was simulated on the unit square up to T=5 and saved as uniformly spaced in space and time. |

# 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 GCE-RT.nc |
|
``` |
