Simulation Data and Code for: Anisotropic Regularization of Incompressible Flow via Directional Momentum Redistribution

This version substantially expands the original DMR Taylor--Green vortex dataset supporting the manuscript: “Anisotropic Regularization of Incompressible Flow via Directional Momentum Redistribution”. The updated dataset includes: • Grid-robustness studies at 32^3, 48^3, and 64^3 resolutions • Enstrophy-production diagnostics comparing Navier--Stokes and DMR dynamics • Shell-averaged kinetic-energy spectra with \(k^{-5/3}\) reference scaling • Spatial anisotropy-localization diagnostics • Publication-ready figures used in the revised manuscript • Updated GPU-accelerated pseudo-spectral simulation code • Expanded README documentation and reproducibility instructions Additional exploratory 128^3 spectral data have also been included. The revised dataset provides stronger numerical evidence for the strain--anisotropy feedback mechanism underlying the DMR framework, including enhanced localized dissipation, suppression of enstrophy growth, and attenuation of high-wavenumber energy transfer relative to classical incompressible Navier--Stokes dynamics.
