The fields behind the movie.

The completed parent and accepted continuation preserve all three velocity and all three forcing components in float64 at each of the 320 saved states.

The current archive

The fixed AMReX hierarchy covers [−1,1]³ with a 128³ base, four nested core refinements, and 27 outer refinement bands. Each state stores 12,055,040 cells; 10,810,304 remain active after covered coarse cells are excluded. The finest central spacing is 1/1024, equivalent to 2048³ only within the innermost cube.

The six-component raw payload is 551.84 MiB per state and approximately 172.45 GiB across the 320-state history, before headers and checkpoints. The retained archive joins the Oliver parent to the accepted Mali continuation. The site publishes its complete velocity and forcing movies, completion record, and native mesh.

Native cells and display samples

The x–y and x–z movie planes use a fixed 256 × 256 display grid and select the finest native cell containing each location. At cell boundaries the positive-side cell is selected. The display grid does not change the solver’s resolution. No peak-following slice, vector arrows, or temporal interpolation is used.

The isometric surfaces reconstruct native scalar magnitudes with fixed thresholds. Irregular fine boxes own only the locations they cover; uncovered regions retain coarse ownership. Same-level box boundaries are joined for reconstruction, and the native core centers are preserved. Rendering method →

Read back before publication

All saved states passed the solver’s archive audit, including exact timestamps, finite values, force reevaluation with zero measured difference, and composite volume 8. Movie preparation independently reads all six components, checks exact rest, reproduces peak speed and kinetic energy, and verifies that two independent exporters produce identical central slices.

The native block, slice, surface, and image hashes retain the provenance of the published movies. These checks establish archive and visualization integrity; spatial convergence and singularity formation remain unproven.
