Detailed Description

template<int dim, typename Number, typename VectorizedArrayType = VectorizedArray<Number>>
class MatrixFreeTools::ElementActivationAndDeactivationMatrixFree< dim, Number, VectorizedArrayType >

A wrapper around MatrixFree to help users to deal with DoFHandler objects involving cells without degrees of freedom, i.e., cells using FE_Nothing as element type. In the following we call such cells deactivated. All other cells are activated. In contrast to MatrixFree, this class skips deactivated cells and faces between activated and deactivated cells are treated as boundary faces.

Member Function Documentation

◆ reinit()

template<int dim, typename Number , typename VectorizedArrayType = VectorizedArray<Number>>

void MatrixFreeTools::ElementActivationAndDeactivationMatrixFree< dim, Number, VectorizedArrayType >::reinit	(	const MatrixFree< dim, Number, VectorizedArrayType > &	matrix_free,
		const AdditionalData &	additional_data = `AdditionalData()`
	)

inline

Reinitialize class based on a given MatrixFree instance. Particularly, the index of the valid FE is determined.

Note: At the moment, only DoFHandler objects are accepted that are initialized with FECollection objects with at most two finite elements (i.e., FE_Nothing and another finite element).

◆ cell_loop()

template<int dim, typename Number , typename VectorizedArrayType = VectorizedArray<Number>>

template<typename VectorTypeOut , typename VectorTypeIn >

void MatrixFreeTools::ElementActivationAndDeactivationMatrixFree< dim, Number, VectorizedArrayType >::cell_loop	(	const std::function< void(const MatrixFree< dim, Number, VectorizedArrayType > &, VectorTypeOut &, const VectorTypeIn &, const std::pair< unsigned int, unsigned int > &)> &	cell_operation,
		VectorTypeOut &	dst,
		const VectorTypeIn &	src,
		const bool	zero_dst_vector = `false`
	)		const

inline

Loop over all activated cells.

For the meaning of the parameters see MatrixFree::cell_loop().

◆ loop()

template<int dim, typename Number , typename VectorizedArrayType = VectorizedArray<Number>>

template<typename VectorTypeOut , typename VectorTypeIn >

void MatrixFreeTools::ElementActivationAndDeactivationMatrixFree< dim, Number, VectorizedArrayType >::loop	(	const std::function< void(const MatrixFree< dim, Number, VectorizedArrayType > &, VectorTypeOut &, const VectorTypeIn &, const std::pair< unsigned int, unsigned int > &)> &	cell_operation,
		const std::function< void(const MatrixFree< dim, Number, VectorizedArrayType > &, VectorTypeOut &, const VectorTypeIn &, const std::pair< unsigned int, unsigned int > &)> &	face_operation,
		const std::function< void(const MatrixFree< dim, Number, VectorizedArrayType > &, VectorTypeOut &, const VectorTypeIn &, const std::pair< unsigned int, unsigned int > &, const bool)> &	boundary_operation,
		VectorTypeOut &	dst,
		const VectorTypeIn &	src,
		const bool	zero_dst_vector = `false`
	)		const

inline

Loop over all activated cells and faces. Faces between activated and deactivated cells are treated as boundary faces with the boundary ID numbers::internal_face_boundary_id.

For the meaning of the parameters see MatrixFree::cell_loop().
