Out-Of-Distribution Evaluation Set For The 2D Vorticity Equation

Out-of-distribution evaluation set for the 2d vorticity equation. The underlying PDE is the vorticity (Navier-Stokes in vorticity form).

This dataset contains out-of-distribution (OOD) samples for evaluating model generalization.

Data is stored in HDF5 (.h5) format.

Origin

This dataset was generated by Armand Kassai Koupaï and has been used in the following papers:
