Constructor & Destructor Documentation

StokesOperator()

template<int dim, int degree_v, typename number >

aspect::MatrixFreeStokesOperators::StokesOperator< dim, degree_v, number >::StokesOperator

(

)

Constructor.

Member Function Documentation

clear()

template<int dim, int degree_v, typename number >

void aspect::MatrixFreeStokesOperators::StokesOperator< dim, degree_v, number >::clear ( )

overridevirtual

Reset object.

Reimplemented from MatrixFreeOperators::Base< dim, ::LinearAlgebra::distributed::BlockVector< number > >.

set_cell_data()

template<int dim, int degree_v, typename number >

void aspect::MatrixFreeStokesOperators::StokesOperator< dim, degree_v, number >::set_cell_data

(

const OperatorCellData< dim, number > &

data

)

Pass in a reference to the problem data.

compute_diagonal()

template<int dim, int degree_v, typename number >

void aspect::MatrixFreeStokesOperators::StokesOperator< dim, degree_v, number >::compute_diagonal ( )

overridevirtual

Computes the diagonal of the matrix. Since matrix-free operators have not access to matrix elements, we must apply the matrix-free operator to the unit vectors to recover the diagonal.

Implements MatrixFreeOperators::Base< dim, ::LinearAlgebra::distributed::BlockVector< number > >.

apply_add()

template<int dim, int degree_v, typename number >

void aspect::MatrixFreeStokesOperators::StokesOperator< dim, degree_v, number >::apply_add ( ::LinearAlgebra::distributed::BlockVector< number > &  dst, const ::LinearAlgebra::distributed::BlockVector< number > &  src  ) const

overrideprivate

Performs the application of the matrix-free operator. This function is called by vmult() functions MatrixFreeOperators::Base.

local_apply()

template<int dim, int degree_v, typename number >

void aspect::MatrixFreeStokesOperators::StokesOperator< dim, degree_v, number >::local_apply ( const ::MatrixFree< dim, number > &  data, ::LinearAlgebra::distributed::BlockVector< number > &  dst, const ::LinearAlgebra::distributed::BlockVector< number > &  src, const std::pair< unsigned int, unsigned int > &  cell_range  ) const

private

Defines the application of the cell matrix.

local_apply_face()

template<int dim, int degree_v, typename number >

void aspect::MatrixFreeStokesOperators::StokesOperator< dim, degree_v, number >::local_apply_face ( const ::MatrixFree< dim, number > &  data, ::LinearAlgebra::distributed::BlockVector< number > &  dst, const ::LinearAlgebra::distributed::BlockVector< number > &  src, const std::pair< unsigned int, unsigned int > &  face_range  ) const

private

This function doesn't do anything, it's created to use the matrixfree loop.

local_apply_boundary_face()

template<int dim, int degree_v, typename number >

void aspect::MatrixFreeStokesOperators::StokesOperator< dim, degree_v, number >::local_apply_boundary_face ( const ::MatrixFree< dim, number > &  data, ::LinearAlgebra::distributed::BlockVector< number > &  dst, const ::LinearAlgebra::distributed::BlockVector< number > &  src, const std::pair< unsigned int, unsigned int > &  face_range  ) const

private

Apply the stabilization on free surface faces.

Member Data Documentation

cell_data

template<int dim, int degree_v, typename number >

const OperatorCellData<dim,number>* aspect::MatrixFreeStokesOperators::StokesOperator< dim, degree_v, number >::cell_data

private

A pointer to the current cell data that contains viscosity and other required parameters per cell.
