◆ heightPass()

void peclet::flow::vof::VofInterfaceArea::heightPass	(	SField	c,

inline

Tiers 1 and 2a: the height function in the preferred direction, then the other two, with the identical column/consistency rules VofCurvature::heightPass uses.

A cell that closes gets its area from the patch's own metric (or its normal); a cell that does not is left with branch = -1 for the PV pass.

◆ metric

VofMetric peclet::flow::vof::VofInterfaceArea::metric

The anisotropic cell metric (Phase 3); {1,1,1} == the pre-Phase-3 arithmetic.

◆ monoTol

double peclet::flow::vof::VofInterfaceArea::monoTol = 1e-6

Definition at line 75 of file interface_area_field.hpp.

Referenced by heightPass().

◆ pureEps

double peclet::flow::vof::VofInterfaceArea::pureEps = 0.0

Purity tolerance of the height-function column walk – the same contract as VofCurvature::pureEps: set it to the tolerance the colour field was advected at (WyAdvector::wispEps), or the HF tier silently decays into the footprint fallback as bulk cells drift into the band between the two.

Solver sets it; floored by core at 1e-10.

◆ cosMin

Referenced by fallbackPass().

◆ interfaceEps

double peclet::flow::vof::VofInterfaceArea::interfaceEps = 0.0

The interfacial predicate's wisp threshold.

The phase-change driver passes ITS OWN (pcEffInterfaceEps), because a cell this driver calls pure would get area 0 while pcIsInterfacial still gave it an mdot — the two classifications must be the same one.
