Detailed Description

Boundary condition record storing low/high face types per coordinate.

BCRec has standard layout — this is a deliberate design constraint that must be preserved for compatibility with Fortran code, host/device transfers, and std::memcpy-based operations.

Constructor & Destructor Documentation

BCRec() [1/4]

__host__ __device__ amrex::BCRec::BCRec ( )

defaultnoexcept

Default constructor leaves all face types set to BCType::bogus.

BCRec() [2/4]

__host__ __device__ amrex::BCRec::BCRec ( int loX, int loY, int loZ, int hiX, int hiY, int hiZ )

inlinenoexcept

Construct a record with explicit low/high face types.

The low-face values are provided first, followed by the high-face values.

Parameters

loX	Low-face boundary type in the x direction.
loY	Low-face boundary type in the y direction (used when AMREX_SPACEDIM >= 2).
loZ	Low-face boundary type in the z direction (used when AMREX_SPACEDIM >= 3).
hiX	High-face boundary type in the x direction.
hiY	High-face boundary type in the y direction (used when AMREX_SPACEDIM >= 2).
hiZ	High-face boundary type in the z direction (used when AMREX_SPACEDIM >= 3).

BCRec() [3/4]

__host__ __device__ amrex::BCRec::BCRec ( const int * a_lo, const int * a_hi )

inlinenoexcept

Construct from arrays of low/high face types.

Parameters

a_lo	Pointer to AMREX_SPACEDIM low-face entries.
a_hi	Pointer to AMREX_SPACEDIM high-face entries.

BCRec() [4/4]

__host__ __device__ amrex::BCRec::BCRec ( const Box & bx, const Box & domain, const BCRec & bc_domain )

inlinenoexcept

Initialize boundary faces relative to a domain record.

Faces coincident with the domain inherit the boundary from bc_domain; interior faces default to BCType::int_dir.

Parameters

bx	Box whose faces inherit domain or interior boundaries.
domain	Domain box describing the physical region.
bc_domain	Boundary record providing domain face types.
