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.

Train/Val/Test-split

1030/100/130 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:

python assemble_data.py --input_dir . --output_file GCE-RT.nc
