Dataset for: A Strain-Activated Anisotropic Regularization Mechanism for Incompressible Flow

This dataset contains the numerical simulation data and source code supporting the manuscript “A Strain-Activated Anisotropic Regularization Model for Incompressible Flow.” The simulations implement a Fourier pseudo-spectral solver for the three-dimensional Taylor–Green vortex with an anisotropy-mediated Directional Momentum Redistribution (DMR) regularization. Included are parameter files, diagnostic outputs, energy and enstrophy histories, vortex-stretching measures, anisotropy-field data, representative figures, and scripts required to reproduce the reported numerical results. The dataset is intended to facilitate transparency, reproducibility, and further investigation of strain-activated anisotropic regularization in incompressible flow.
