Detailed Description

template<class Limiter, class NumericalFlux, class Model>
struct pops::detail::AssembleRhsMaskedKernel< Limiter, NumericalFlux, Model >

AssembleRhsMaskedKernel: variant of AssembleRhsKernel AWARE of a domain mask.

Inactive cell -> residual 0 (not advanced by the caller). Active cell -> R = -div Fhat + S, BUT the normal flux of a face whose neighbor cell is INACTIVE is set to ZERO (FV wall: zero normal flux at the active/inactive boundary) -> mass conservation over the active sub-domain. Named functor (same device contract as AssembleRhsKernel). POPS_HD.

NB: without a diffusive term (transport-only models); a DiffusiveModel keeps its UNmasked Laplacian here (separate refinement – the conservative mask targets the hyperbolic flux only).
