Constructor & Destructor Documentation

◆ CollocatedVectorGrid2()

jet::CollocatedVectorGrid2::CollocatedVectorGrid2 ( )

Constructs an empty grid.

◆ ~CollocatedVectorGrid2()

virtual jet::CollocatedVectorGrid2::~CollocatedVectorGrid2 ( )

virtual

Default destructor.

Member Function Documentation

◆ constDataAccessor()

ConstVectorDataAccessor jet::CollocatedVectorGrid2::constDataAccessor ( ) const

Returns the read-only data array accessor.

◆ curl()

double jet::CollocatedVectorGrid2::curl ( const Vector2D & x ) const

overridevirtual

Returns curl at given position x.

Reimplemented from jet::VectorField2.

◆ curlAtDataPoint()

double jet::CollocatedVectorGrid2::curlAtDataPoint	(	size_t	i,
		size_t	j
	)		const

Returns curl at data point location.

◆ dataAccessor()

VectorDataAccessor jet::CollocatedVectorGrid2::dataAccessor ( )

Returns the read-write data array accessor.

◆ dataOrigin()

virtual Vector2D jet::CollocatedVectorGrid2::dataOrigin ( ) const

pure virtual

Returns data position for the grid point at (0, 0).

Note that this is different from origin() since origin() returns the lower corner point of the bounding box.

Implemented in jet::CellCenteredVectorGrid2, and jet::VertexCenteredVectorGrid2.

◆ dataPosition()

DataPositionFunc jet::CollocatedVectorGrid2::dataPosition ( ) const

Returns the function that maps data point to its position.

◆ dataSize()

virtual Size2 jet::CollocatedVectorGrid2::dataSize ( ) const

pure virtual

Returns the actual data point size.

Implemented in jet::CellCenteredVectorGrid2, and jet::VertexCenteredVectorGrid2.

◆ divergence()

double jet::CollocatedVectorGrid2::divergence ( const Vector2D & x ) const

overridevirtual

Returns divergence at given position x.

Reimplemented from jet::VectorField2.

◆ divergenceAtDataPoint()

double jet::CollocatedVectorGrid2::divergenceAtDataPoint	(	size_t	i,
		size_t	j
	)		const

Returns divergence at data point location.

◆ forEachDataPointIndex()

void jet::CollocatedVectorGrid2::forEachDataPointIndex ( const std::function< void(size_t, size_t)> & func ) const

Invokes the given function func for each data point.

This function invokes the given function object func for each data point in serial manner. The input parameters are i and j indices of a data point. The order of execution is i-first, j-last.

◆ getData()

void jet::CollocatedVectorGrid2::getData ( std::vector< double > * data ) const

overrideprotectedvirtual

Fetches the data into a continuous linear array.

Implements jet::Grid2.

◆ operator()() [1/2]

Vector2D& jet::CollocatedVectorGrid2::operator()	(	size_t	i,
		size_t	j
	)

Returns the grid data at given data point.

const Vector2D& jet::CollocatedVectorGrid2::operator()	(	size_t	i,
		size_t	j
	)		const

Returns the grid data at given data point.

◆ parallelForEachDataPointIndex()

void jet::CollocatedVectorGrid2::parallelForEachDataPointIndex ( const std::function< void(size_t, size_t)> & func ) const

Invokes the given function func for each data point parallelly.

This function invokes the given function object func for each data point in parallel manner. The input parameters are i and j indices of a data point. The order of execution can be arbitrary since it's multi-threaded.

◆ sample()

Vector2D jet::CollocatedVectorGrid2::sample ( const Vector2D & x ) const

overridevirtual

Returns sampled value at given position x.

Implements jet::VectorField2.

◆ sampler()

std::function<Vector2D(const Vector2D&)> jet::CollocatedVectorGrid2::sampler ( ) const

overridevirtual

Returns the sampler function.

This function returns the data sampler function object. The sampling function is linear.

Reimplemented from jet::VectorField2.

void jet::CollocatedVectorGrid2::setCollocatedVectorGrid ( const CollocatedVectorGrid2 & other )

protected

Sets the data storage and predefined samplers with given grid.

◆ setData()

void jet::CollocatedVectorGrid2::setData ( const std::vector< double > & data )

overrideprotectedvirtual

Sets the data from a continuous linear array.

Implements jet::Grid2.

◆ swapCollocatedVectorGrid()

void jet::CollocatedVectorGrid2::swapCollocatedVectorGrid ( CollocatedVectorGrid2 * other )

protected

Swaps the data storage and predefined samplers with given grid.
