TurtLES
A 3D turbulent-wake benchmark where operators fail over long rollouts
Paper title TurtLES: A Large-Scale Benchmark for Turbulent 3D Neural PDE Surrogates
Paper arXiv 2611.09567PDF
TurtLES is a 14 TB set of 3D turbulent cylinder wakes in the shear-layer transition regime from implicit large-eddy simulation: 400 trajectories of 400 time steps, 3-11 million points per frame, varying geometry, Reynolds number and angle of attack. Neural operators are benchmarked on autoregressive rollouts.
