Namespaces

namespace	pops::detail

Enumerations
enum class	pops::BCType { pops::Periodic , pops::Foextrap , pops::Dirichlet }
	Boundary condition type for a face: Periodic (handled by fill_boundary), Foextrap (zero gradient, outflow/order-0 wall), Dirichlet (value imposed at the face by reflection). More...

Functions
void	pops::fill_physical_bc_range (MultiFab &mf, const Box2D &domain, const BCRec &bc, int c0, int c1)
	Fills the OUT-OF-domain ghosts of the NON-periodic faces of `mf` according to `bc` (Foextrap or Dirichlet), for the COMPONENT RANGE [c0, c1).

void	pops::fill_physical_bc (MultiFab &mf, const Box2D &domain, const BCRec &bc)
	Fills the physical-face ghosts of ALL components per `bc` (historical entry point, bit-identical).

void	pops::fill_physical_bc (MultiFab &mf, const Box2D &domain, const BCRec &bc, int comp)
	ADC-369: fills the physical-face ghosts of a SINGLE component `comp` per `bc` – the per-field aux halo override.

BCRec	pops::aux_halo_override (const BCRec &shared, const AuxHaloPolicy &p)
	Builds the effective override BCRec for a per-field aux halo: starts from the SHARED aux BC `shared` (so periodic faces stay periodic) and replaces each NON-PERIODIC face with the policy `p` (type + Dirichlet value).

void	pops::fill_ghosts (MultiFab &mf, const Box2D &domain, const BCRec &bc)
	COMPLETE ghost filling: fill_boundary (interior + periodic, periodicity deduced from `bc`) THEN fill_physical_bc (physical edges).

Detailed Description

PHYSICAL boundary conditions at the domain edge (BCType, BCRec, fill_physical_bc, fill_ghosts).

fill_boundary already fills the INTERIOR and periodic ghosts; here we fill the ghosts that fall OUTSIDE the domain on non-periodic faces. Foextrap: zero-order extrapolation (zero gradient), ghost = mirror interior cell (outflow / order-0 wall). Dirichlet: value imposed at the FACE, ghost = 2 v - mirror interior (the ghost/interior average equals v at the face). fill_ghosts composes both in the right order (interior/periodic THEN physical edge) and fills the corners via x-faces then y-faces over the full extension. The edge kernels are device-clean NAMED FUNCTORS (nvcc limitation).
