Detailed Description

template<typename T>
class LinCCTransfer< T >

Class templates for multilinear transfer operators for cell centered grid functions.

The templates depend on a type T. This type should satisfy the conditions listed in small_matrix.hpp for small matrices.

Member Function Documentation

template<typename T>

void LinCCTransfer< T >::PrintParam

(

)

[inline, virtual]

Prints the name of the transfer object and (optionally) the parameters.

Implements SysTransfer< T >.

template<typename T>

bool LinCCTransfer< T >::ProperGrids	(	const Array< int > &	p_domain_size,
		const Array< int > &	p_range_size
	)			[inline, virtual]

Returns true if the grid sizes may correspond to the domain and the range of the prolongation (or the range and the domain of the restriction).

Note:

The grid sizes corresponding to the same dimensions should be either halved or equal.

Parameters:

[in]	p_domain_size	For the domain of the prolongation
[in]	p_range_size	For the range of the prolongation

Implements Transfer< T >.

template<typename T>

void LinCCTransfer< T >::Prolong	(	MultiVector< T > &	src,
		MultiVector< T > &	dst
	)			[inline, virtual]

The prolongation.

The prolongation is implemented as computation of halved sums of manyfolds of the grid. We do it recursively and start with the manyfolds of the smallest dimensionality.

Parameters:

[in]	src	The vector to prolong
[in]	dst	The result (the sizes must be initialized!)

Implements Transfer< T >.

template<typename T>

void LinCCTransfer< T >::Restrict	(	MultiVector< T > &	src,
		MultiVector< T > &	dst
	)			[inline, virtual]

The restriction.

Parameters:

[in]	src	The vector to restrict
[in]	dst	The result (the sizes must be initialized!)

Implements Transfer< T >.

template<typename T>

void LinCCTransfer< T >::copy_from_coarse_grid	(	int	init_dim,
		MultiVector< T > &	src,
		MultiIndex &	src_index,
		MultiVector< T > &	dst,
		MultiIndex &	dst_index
	)			[inline, static]

Copies the values of the coarse grid cells to the corresponding ('lower left' in 2D) cells of the fine grid.

Parameters:

[in]	init_dim	The dimension index to start with
[in]	src	The coarse grid vector
[in]	src_index	The initial index for the coarse grid
[in]	dst	The fine grid vector
[in]	dst_index	The initial index for the fine grid

template<typename T>

void LinCCTransfer< T >::spread_subgrids	(	int	init_dim,
		const Array< int > &	coarse_sizes,
		MultiVector< T > &	vec,
		MultiIndex &	index
	)			[inline, static]

Recursively copies the values from the 'coarse grid cells' to the neighbouring cells.

The 'coarse grid cells' should be initialized

Parameters:

[in]	init_dim	The dimension index to start with
[in]	coarse_sizes	The coarse grid sizes
[in]	vec	The vector to process
[in]	index	The initial index

template<typename T>

void LinCCTransfer< T >::integr_subgrids	(	int	init_dim,
		const Array< int > &	coarse_sizes,
		MultiVector< T > &	vec,
		MultiIndex &	index
	)			[inline, static]

Computes the restriction on the subgrids.

Parameters:

[in]	init_dim	The dimension index to start with
[in]	coarse_sizes	The coarse grid sizes
[in]	vec	The vector to process
[in]	index	The initial index

template<typename T>

void LinCCTransfer< T >::copy_from_fine_grid	(	int	init_dim,
		MultiVector< T > &	src,
		MultiIndex &	src_index,
		MultiVector< T > &	dst,
		MultiIndex &	dst_index
	)			[inline, static]

Copies the values of the 'coarse grid cells' of a fine grid to the corresponding cells of the coarse grid.

Parameters:

[in]	init_dim	The dimension index to start with
[in]	src	The fine grid vector
[in]	src_index	The initial index for the fine grid
[in]	dst	The coarse grid vector
[in]	dst_index	The initial index for the coarse grid
