Parameters

size	The number of elements to copy.
srcPtr	Pointer to the original block of memory.
dstPtr	Pointer to the target block of memory.

Template Parameters

ValueType

The type of the underlying elements.

Returns

A function that takes a source and an destination executor

fieldBinaryOp()

template<typename ValueType , typename BinaryOp >

void NeoN::detail::fieldBinaryOp	(	Vector< ValueType > &	vect1,
		const Vector< std::type_identity_t< ValueType > > &	vect2,
		BinaryOp	op
	)

generateBoundaryData()

BoundaryMesh NeoN::detail::generateBoundaryData	(	const Executor	exec,
		const int	dim,
		const MeshParams &	p,
		const std::vector< Vec3 > &	centers,
		const localIdx	nInternalFaces,
		const localIdx	nBoundaryFaces,
		const std::vector< localIdx >	offset,
		FaceData &	faces
	)

Generate boundary face data for a 3D uniform mesh.

Constructs boundary face geometry, connectivity, and interpolation data for all six domain boundaries (x-, y-, z-directions).

Supports 1D, 2D, and 3D configurations depending on dimension parameter.

Parameters

exec	Execution context
dim	Spatial dimension (1, 2, or 3)
p	Mesh parameters
centers	Cell center coordinates
nInternalFaces	Number of internal faces
nBoundaryFaces	Number of boundary faces
offset	Boundary face offset mapping for patch indexing
faces	face data including boundary faces

Returns

BoundaryMesh containing all boundary-related geometric data

generateCellData()

CellData NeoN::detail::generateCellData

(

const MeshParams &

p

)

Generate cell volumes and cell-center coordinates.

Computes geometric properties of each cell in a uniform Cartesian mesh, assuming constant spacing in all coordinate directions.

Parameters

p	Mesh parameters

Returns

CellData containing volumes and cell centers

generateInternalFaces()

FaceData NeoN::detail::generateInternalFaces	(	const MeshParams &	p,
		const localIdx	nInternalFaces,
		const localIdx	nFaces
	)

Generate internal face data for a 3D uniform mesh.

Constructs face normals, centers, magnitudes, and owner/neighbour connectivity for all internal faces in x-, y-, and z-directions.

Face ordering:

• First: x-normal faces
• Second: y-normal faces
• Third: z-normal faces

Parameters

p	Mesh parameters
nInternalFaces	Number of internal faces
nFaces	Total number of faces

Returns

FaceData containing internal face geometry and connectivity

generatePoints()

std::vector< Vec3 > NeoN::detail::generatePoints

(

const MeshParams &

p

)

Generate mesh vertex coordinates for a uniform Cartesian grid.

Creates a structured set of points spanning a 3D rectangular domain with uniform spacing in x, y, and z directions.

Parameters

p	Mesh parameters defining resolution and domain size

Returns

Vector of point coordinates in structured ordering
