State variables (density, X-, Y- and Z-velocity, and pressure) for rollouts from simulators that last for a time 4x greater than the duration seen during training. Simulators include the Ground Truth physics-based simulator (Athena++ at resolution of 128^3), coarsened Athena++ at resolutions of 64^3 and 32^3, and Dil-ResNet model rollouts at a resolution of 32^3 with and without noise.

Note that even though the distribution of states in CompDecay-3D is not stationary in time, as the flow decays progressively into smaller and smaller structures, Dil-ResNet remains competitive with Athena++32 for turbulence that has decayed for up to twice longer (t<2) than ever observed during training.
