Detailed Description

struct pops::detail::EbFaceFluxXKernel< Limiter, NumericalFlux, Model, LevelSet >

FACE FLUX kernel for x (dir 0) of the EB transport: numerical flux at the face between (i-1, j) and (i, j), WEIGHTED by the aperture alpha_x of that face.

We store alpha_x * Fx so the EB divergence is a simple difference (like the r weighting of the polar operator). NAMED FUNCTOR (device-clean).

The aperture of face i is computed FROM THE SIDE of the active cell: if (i, j) is active, we take the aperture seen from (i, j) toward its neighbor (i-1); if (i, j) is inactive but (i-1, j) is active, we take the aperture seen from (i-1) toward (i). If BOTH are inactive, the face is outside the active domain (alpha = 0). This symmetry guarantees the uniqueness of alpha on the shared face (conservation).
