Description
v14.0.0: Theoretical Alignment & Verified 3D SOR Simulation Core
This major release synchronizes the repository with the latest structural corrections and mathematical defenses added to the WDF Theory manuscript. This update formally establishes the verified source-code components and empirical plots for the discrete mesh framework.
📝 Manuscript Synchronization & Text Corrections
- Numerical Scale Alignment: Fully updated the abstract and Section 9 of the manuscript to precisely match the active $128^3$ uniform Cartesian mesh configurations, replacing previous prospective resolution placeholders.
- Boundary Clarifications: Explicitly specified that the baryonic gas backgrounds and initial momentum velocity fields $J$ are modeled as idealized, analytical Gaussian profiles designed for proof-of-concept geometric validation.
- Casping and Tone Adjustments: Refined the comparative physics terminology from quantitative matching to qualitative reproduction of the spatial decoupling patterns observed in cluster weak-lensing data.
🚀 Repository Source Contents (Simulation Engine)
1. 3D Poisson SOR Solver (draw_plots.py)
- Grid Scale: Executed on a uniform $128^3$ mesh representing a cosmic core volume of $(6 \text{ Mpc})^3$.
- Algorithm Dynamic: Employs a point-wise Successive Over-Relaxation (SOR) relaxation scheme accelerated via Numba JIT compilation, driven by a mathematically verified negative-feedback loop (
-=) using the optimal relaxation factor $\omega_{\rm opt} = 1.84$. - Topological Source Evaluation: Computes the non-linear source terms from a staggered finite-difference approximation of the Yee-lattice loop connections (modeled as the helicity density $J \cdot (\nabla \times J)$).
2. Automated Empirical Validation Outputs
The repository script executes a full-convergent numerical cycle, enforcing a strict residual truncation floor bounded by $\max | \nabla^2_{\rm disc} \phi^n - \rho_{\rm source} | < 10^{-7}$. It directly outputs the final peer-review ready validation plots included in the paper:
figure_sor_convergence.pdf: Captures the real-time monotonic exponential $L_2$ residual decay curve, safely clearing the convergence criterion threshold within $\sim 750$ global iteration sweeps.figure_cluster_topology.pdf: Features the dual-panel $z=0$ topological bifurcation slices:- Panel (a) [Bullet Cluster proxy]: Demonstrating the distinct spatial decoupling and non-symmetrical distance offset between the emergent 0-form gravity potential well (red contours) and the stripped gas flow (blue fill).
- Panel (b) [Abell 520 proxy]: Capturing the central core-retention and metric skeleton trapping within the geometric merging center under isotropic disordered momentum flux cancellation.
Notice to Reviewers: All numerical plots and convergence metrics presented in Section 9 of the updated paper are fully and transparently reproducible using the open-source python script provided in this tree. No hidden data-fitting parameters or unverified empirical constants are utilized; the framework runs strictly on the algebraic constraints of the $O_h$ point group and discrete limited-difference relaxation.
