Observable-Dependent Realization Repeatability in Lattice-Boltzmann Turbulent Mixing: a Locality-Threshold Ordering (data and code)

Reproducibility archive for the manuscript of the same title: raw per-seed data, Python analysis/figure scripts, and FluidX3D (OpenCL) + OpenLB (CUDA/OpenMP) setup sources to regenerate every figure and table, plus the compiled manuscript. The study shows run-to-run scatter in chaotic LBM-LES turbulent mixing is an observable-specific coefficient of variation, ordered by locality (point vs. volume average) and threshold (tail vs. bulk), spanning ~1% (global, early) to ≥48% (local, late) in one Taylor-Couette flow.
