Fluid 1D MMS Convergence¶

This package promotes the existing fluid-1D manufactured-solution refinement study from a standalone script into a reviewable validation bundle.

It serves two purposes:

• direct verification that the promoted 1D density, pressure, and momentum operators converge under refinement;
• a publication-ready convergence figure that can be reused in the docs and in the future manuscript instead of leaving the evidence hidden in a JSON file or a test assertion.

The generated package contains:

• a summary JSON with per-resolution errors and observed orders;
• a compact NPZ payload for downstream plotting and regression checks;
• a publication-grade convergence plot.

This is a verification surface, not a code-to-code comparison surface. It belongs to the same evidence family emphasized in the verification literature and in the convergence sections of major edge/SOL code papers: refinement studies are used to establish operator correctness before broader benchmark validation is interpreted.

Run the demo with:

python scripts/run_fluid_1d_mms_convergence.py
