Function Documentation

ComputeNBorrowEightFacesExtension()

AMREX_GPU_DEVICE int ComputeNBorrowEightFacesExtension	(	const amrex::Dim3	cell,
		const amrex::Real	S_ext,
		const amrex::Array4< amrex::Real > &	S_red,
		const amrex::Array4< amrex::Real > &	S,
		const amrex::Array4< int > &	flag_info_face,
		int	idim
	)

For the face of cell pointing in direction idim, return the number of faces we need to intrude with the eight-ways extension.

Parameters

[in]	cell	Dim3 storing the indices of the face to extended
[in]	S_ext	amount of area needed for the extension
[in]	S_red	Array4 storing the amount of area each face can still give away
[in]	S_red	Array4 storing the area of face
[in]	flag_info_face	Array4 storing face information
[in]	idim	normal direction to the face in consideration (0 for x, 1 for y, 2 for z)

ComputeNBorrowOneFaceExtension()

AMREX_GPU_DEVICE int ComputeNBorrowOneFaceExtension	(	const amrex::Dim3	cell,
		const amrex::Real	S_ext,
		const amrex::Array4< amrex::Real > &	S_red,
		const amrex::Array4< int > &	flag_info_face,
		const amrex::Array4< int > &	flag_ext_face,
		int	idim
	)

For the face of cell pointing in direction idim, return the number of faces we need to intrude with the one-way extension. Returns only one or zero: one if the face can be extended with the the one-way extension, zeros if it can't.

Parameters

[in]	cell	Dim3 storing the indices of the face to extended
[in]	S_ext	amount of area needed for the extension
[in]	S_red	Array4 storing the amount of area each face can still give away
[in]	flag_info_face	Array4 storing face information
[in]	flag_ext_face	Array4 storing face information
[in]	idim	normal direction to the face in consideration (0 for x, 1 for y, 2 for z)
