Detailed Description

template<typename Number>
class hyperdeal::internal::MatrixFreeFunctions::ReadWriteOperation< Number >

Helper class for transferring data from global to cell-local vectors and vice versa.

Constructor & Destructor Documentation

ReadWriteOperation()

template<typename Number >

hyperdeal::internal::MatrixFreeFunctions::ReadWriteOperation< Number >::ReadWriteOperation	(	const hyperdeal::internal::MatrixFreeFunctions::DoFInfo &	dof_info,

Member Function Documentation

process_cell()

template<typename Number >

template<int dim, int degree, typename VectorOperation , typename VectorizedArrayType >

void hyperdeal::internal::MatrixFreeFunctions::ReadWriteOperation< Number >::process_cell	(	const VectorOperation &	operation,
		const std::vector< dealii::ArrayView< const Number > > &	data_others,
		VectorizedArrayType *	dst,
		const unsigned int	cell_batch_number ) const

Transfer data for a (macro-)cell. If dofs are read, write, or distributed is determined by operation.

process_face()

template<typename Number >

template<int dim_x, int dim_v, int degree, typename VectorOperation , typename VectorizedArrayType >

void hyperdeal::internal::MatrixFreeFunctions::ReadWriteOperation< Number >::process_face	(	const VectorOperation &	operation,
		const std::vector< dealii::ArrayView< const Number > > &	data_others,
		VectorizedArrayType *	dst,
		const unsigned int *	face_no,
		const unsigned int *	face_orientation,
		const unsigned int	face_orientation_offset,
		const unsigned int	cell_batch_number,
		const unsigned int	cell_side,
		const unsigned int	face_batch_number,
		const unsigned int	face_side ) const

Transfer data for a (macro-)face. If dofs are read, write, or distributed is determined by operation.

The complexity compared to process_cell (additional arguments) rises due to the fact:

• faces are relevant in different context: ECL/FCL interior/exterior
• that faces might be embedded within cells (e.g., interior faces) or might be stored on their own (ghost faces). In the first case, the dofs from face_no have to be extracted.
• faces might be not orientated in relation to the neighbor, which requires a re-orientation here.
• In comparison to FCL and ECL interior faces, each faces of a ECL exterior macro face might have a different orientation and face number.
