Detailed Description

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices, typename ScalarType = double>
struct MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices, ScalarType >

Helper copy data struct.

This class is a good default drop in CopyData object for the WorkStream::run() and MeshWorker::mesh_loop() functions.

It arrays of (local) full matrices, vectors, and local degrees of freedom index vectors, with size determined by the corresponding template argument.

In particular, you can specify the following template arguments

• Template Parameters

  n_matrices

  Size of the array of matrices

• Template Parameters

  n_vectors

  size of the array of vectors

• Template Parameters

  n_dof_indices

  size of the array of local dof indices

• Template Parameters

  ScalarType

  The data type stored by the vectors and matrices. This must be a real or complex floating point number.

Constructor & Destructor Documentation

CopyData() [1/4]

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices, typename ScalarType = double>

MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices, ScalarType >::CopyData ( )

explicitdefault

Default constructor. All of the matrices, vectors and local_dof_indices are empty, and should be initialized using one of the reinit() functions.

CopyData() [2/4]

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices, typename ScalarType = double>

MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices, ScalarType >::CopyData ( const unsigned int  size )

explicit

Initialize everything with the same size. This is usually the number of local degrees of freedom.

CopyData() [3/4]

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices, typename ScalarType = double>

MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices, ScalarType >::CopyData ( const ndarray< unsigned int, n_matrices, 2 > &  matrix_sizes, const std::array< unsigned int, n_vectors > &  vector_sizes, const std::array< unsigned int, n_dof_indices > &  dof_indices_sizes  )

explicit

For every object, specify the size they should have.

CopyData() [4/4]

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices, typename ScalarType = double>

MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices, ScalarType >::CopyData ( const CopyData< n_matrices, n_vectors, n_dof_indices, ScalarType > &  other )

default

Copy constructor.

Member Function Documentation

operator=()

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices, typename ScalarType = double>

CopyData & MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices, ScalarType >::operator= ( const CopyData< n_matrices, n_vectors, n_dof_indices, ScalarType > &  other )

default

Copy operator.

reinit() [1/3]

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices, typename ScalarType = double>

void MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices, ScalarType >::reinit

(

const unsigned int

size

)

Reinitialize everything the same size. This is usually the number of local degrees of freedom.

reinit() [2/3]

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices, typename ScalarType = double>

void MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices, ScalarType >::reinit	(	const unsigned int	index,
		const unsigned int	size
	)

Reinitialize the index'th matrix, vector and local DoF index vector with the same size. This is usually the number of local degrees of freedom.

Note

In the event that there are a different number of matrices, vectors and local_dof_indices, this function will not throw an error when the index is over the size of one or two of these data structures. However, if the index exceeds the size of all three of them then an error will be thrown.

reinit() [3/3]

template<int n_matrices = 1, int n_vectors = n_matrices, int n_dof_indices = n_matrices, typename ScalarType = double>

void MeshWorker::CopyData< n_matrices, n_vectors, n_dof_indices, ScalarType >::reinit	(	const unsigned int	index,
		const unsigned int	size_rows,
		const unsigned int	size_columns
	)

Reinitialize the index'th matrix with size_rows x size_columns, and the vector and local DoF index vector with size_columns. These sizes usually correspond to some local degrees of freedom (e.g., the number of cell DoFs for size_rows and number of neighbor cell DoFs for size_columns).

Note

In the event that there are a different number of matrices, vectors and local_dof_indices, this function will not throw an error when the index is over the size of one or two of these data structures. However, if the index exceeds the size of all three of them then an error will be thrown.
