Trajectories used in the ICML 2026 paper Test-time Generalization for
Physics through Neural Operator Splitting (Serrano, Han, Oyallon, Ho, Morel).
2D simulations of three closely-related physics regimes on a periodic square
domain $[0, 2\pi]^2$, resolved at 256×256 (downsampled from a 512×512 spectral
solver):
euler — inviscid 2D vorticity transport ($\nu = 0$).
navier_stokes — incompressible Navier–Stokes in vorticity form. Diffusion
viscosities are sampled at 16… See the full description on the dataset page:
