◆ moment

double peclet::flow::vof::VofBlockStats::moment[6] {0, 0, 0, 0, 0, 0}

Central second moments Σ C (x−x̄)(y−ȳ)/Σ C, order xx, yy, zz, xy, xz, yz (the deformation).

Definition at line 278 of file block_container.hpp.

◆ recentred

bool peclet::flow::vof::VofBlockStats::recentred = false

the box moved at the end of the last step

Definition at line 279 of file block_container.hpp.

◆ cells

long peclet::flow::vof::VofBlockStats::cells = 0

inner-box cell count (the master's work)

Definition at line 280 of file block_container.hpp.

◆ discarded

double peclet::flow::vof::VofBlockStats::discarded = 0.0

Cumulative colour dropped by re-centrings, i.e.

the Weymouth-Yue round-off WISPS left in the bubble's wake that fell below VofBlockSet::bubbleEps. Never physical liquid (see the bubbleEps note); reported because a container that silently loses mass is not acceptable.

◆ area

double peclet::flow::vof::VofBlockStats::area = 0.0

Interface area of the marker, in cell-size units squared: the sum of the PLIC polygon areas over the inner box (plicPolygon + polygonAreaCentroid on the MYC normal, i.e.

exactly the planes the curvature cascade reconstructs). Rung W1 item (d) — the gallery's per-bubble Lagrangian output. A sphere of radius R reads 4 pi R^2 to the PLIC discretization error (~1 % at R/h = 8), NOT exactly; it is a measure of the reconstructed surface, not of a fit.

Definition at line 290 of file block_container.hpp.

◆ debrisCells

long peclet::flow::vof::VofBlockStats::debrisCells = 0

Marker DEBRIS (doc/vof_overlap_design.md §5.2 as amended by §11): an interfacial cell (vofIsInterface(C, curvProto.interfaceEps)) with NO cell of the marker's own colour above VofBlockSet::kDebrisMaxC (1/2) within two cells (its 5^3 fit stencil) – colour with no resolvable interface of its marker near it, the cell the curvature cascade cannot fit.

Evaluated per step on the master, after the WY advection and before the re-centring, while the block CSF is on; removed (colour -> 0, volume returned to the marker's attached interface) when VofBlockSet::debrisRemove is on. debris cells removed this step (detected, if removal is off)

Definition at line 298 of file block_container.hpp.

◆ debrisVolume

double peclet::flow::vof::VofBlockStats::debrisVolume = 0.0

their colour, summed in list order (cell volumes), this step

Definition at line 299 of file block_container.hpp.

double peclet::flow::vof::VofBlockStats::debrisReturned = 0.0

cumulative sum of debrisVolume over the removals

◆ fullAxis

long peclet::flow::vof::VofBlockStats::fullAxis = 0

Cumulative re-centrings whose box had to span a whole periodic axis (vof_overlap_design §12.3): the box is snapped to [0, L) there and the colour copied with the periodic wrap.

◆ residueReturned

double peclet::flow::vof::VofBlockStats::residueReturned = 0.0
