Based on the forced incompressible Navier-Stokes equations, this dataset contains trajectories starting from initial conditions with piecewise constant vorticity, see
https://arxiv.org/abs/2405.19101.
The assembled NetCDF file has a single variable called solution with dimensionality
20000 (number of trajectories)
21 (time steps)
2 (horizontal velocity, vertical velocity)
128 (x-dim)
128 (y-dim)
It was simulated on the unit square up to T=1… See the full description on the dataset page:
