Detailed Description

template<int dim, int fe_degree, int n_q_points_1d = fe_degree + 1, int n_components = 1, typename VectorType = LinearAlgebra::distributed::Vector<double>, typename VectorizedArrayType = VectorizedArray<typename VectorType::value_type>>
class MatrixFreeOperators::MassOperator< dim, fe_degree, n_q_points_1d, n_components, VectorType, VectorizedArrayType >

This class implements the operation of the action of a mass matrix.

Note that this class only supports the non-blocked vector variant of the Base operator because only a single FEEvaluation object is used in the apply function.

virtualinherited

Release all memory and return to a state just like after having called the default constructor.

const std::vector< unsigned int > &  selected_row_blocks = std::vector<unsigned int>(),
const std::vector< unsigned int > &  selected_column_blocks = std::vector<unsigned int>() 
)
inherited

Initialize operator on fine scale.

The optional selection vector allows to choose only some components from the underlying MatrixFree object, e.g. just a single one. The entry selected_row_blocks[i] in the vector chooses the DoFHandler and AffineConstraints object that was given as the selected_row_blocks[i]-th argument to the MatrixFree::reinit() call. Different arguments for rows and columns also make it possible to select non-diagonal blocks or rectangular blocks. If the row vector is empty, all components are selected, otherwise its size must be smaller or equal to MatrixFree::n_components() and all indices need to be unique and within the range of 0 and MatrixFree::n_components(). If the column selection vector is empty, it is taken the same as the row selection, defining a diagonal block.

Definition at line 236 of file operators.h.

◆ initialize() [2/3]

void MatrixFreeOperators::Base< dim, LinearAlgebra::distributed::Vector< double > , VectorizedArray< typename VectorType::value_type > >::initialize ( std::shared_ptr< const MatrixFree< dim, value_type, VectorizedArray< typename VectorType::value_type > > >  data,
const MGConstrainedDoFs &  mg_constrained_dofs,
const unsigned int  level,
const std::vector< unsigned int > &  selected_row_blocks = std::vector<unsigned int>() 
)
inherited

Initialize operator on a level level for a single FiniteElement.

The optional selection vector allows to choose only some components from the underlying MatrixFree object, e.g. just a single one. The entry selected_row_blocks[i] in the vector chooses the DoFHandler and AffineConstraints object that was given as the selected_row_blocks[i]-th argument to the MatrixFree::reinit() call. Since a multigrid operator is always associated to inverting a matrix and thus represents a diagonal block, the same vector for rows and columns is used as opposed to the non-level initialization function. If empty, all components are selected.

inherited

Initialize operator on a level level for multiple FiniteElement objects.

The optional selection vector allows to choose only some components from the underlying MatrixFree object, e.g. just a single one.
