Detailed Description

template<int dim, int spacedim = dim, typename number = double>
class MeshWorker::LocalIntegrator< dim, spacedim, number >

A local integrator object, which can be used to simplify the call of loop(). Instead of providing the three local integration functions separately, we bundle them as virtual functions in this class.

Additionally, since we cannot have a virtual null function, we provide flags, which allow us to indicate, whether we want to integrate on boundary and interior faces. These flags are true by default, but can be modified by applications to speed up the loop.

If a function is not overloaded in a derived class, but its usage flag is true, the function will cause an exception ExcPureFunction.

Constructor & Destructor Documentation

§ LocalIntegrator() [1/2]

template<int dim, int spacedim, typename number >

MeshWorker::LocalIntegrator< dim, spacedim, number >::LocalIntegrator ( )

The constructor setting default values, namely all integration flags to true.

Definition at line 62 of file mesh_worker.cc.

template<int dim, int spacedim, typename number >

MeshWorker::LocalIntegrator< dim, spacedim, number >::LocalIntegrator	(	bool	use_cell,
		bool	use_boundary,
		bool	use_face
	)

The constructor setting integration flags to specified values.

Definition at line 69 of file mesh_worker.cc.

§ ~LocalIntegrator()

template<int dim, int spacedim, typename number >

MeshWorker::LocalIntegrator< dim, spacedim, number >::~LocalIntegrator ( )

The empty virtual destructor.

Member Function Documentation

§ cell()

template<int dim, int spacedim, typename number >

void MeshWorker::LocalIntegrator< dim, spacedim, number >::cell	(	DoFInfo< dim, spacedim, number > &	dinfo,
		IntegrationInfo< dim, spacedim > &	info
	)		const

virtual

Virtual function for integrating on cells. Throws exception PureFunctionCalled if not overloaded by a derived class.

Definition at line 81 of file mesh_worker.cc.

§ boundary()

template<int dim, int spacedim, typename number >

void MeshWorker::LocalIntegrator< dim, spacedim, number >::boundary	(	DoFInfo< dim, spacedim, number > &	dinfo,
		IntegrationInfo< dim, spacedim > &	info
	)		const

virtual

Virtual function for integrating on boundary faces. Throws exception PureFunctionCalled if not overloaded by a derived class.

Definition at line 90 of file mesh_worker.cc.

§ face()

template<int dim, int spacedim, typename number >

void MeshWorker::LocalIntegrator< dim, spacedim, number >::face	(	DoFInfo< dim, spacedim, number > &	dinfo1,
		DoFInfo< dim, spacedim, number > &	dinfo2,
		IntegrationInfo< dim, spacedim > &	info1,
		IntegrationInfo< dim, spacedim > &	info2
	)		const

virtual

Virtual function for integrating on interior faces. Throws exception PureFunctionCalled if not overloaded by a derived class.

Definition at line 99 of file mesh_worker.cc.

Member Data Documentation

§ use_cell

template<int dim, int spacedim = dim, typename number = double>

bool MeshWorker::LocalIntegrator< dim, spacedim, number >::use_cell

The flag indicating whether the cell integrator cell() is to be used in the loop. Defaults to true.

Definition at line 96 of file local_integrator.h.

§ use_boundary

template<int dim, int spacedim = dim, typename number = double>

bool MeshWorker::LocalIntegrator< dim, spacedim, number >::use_boundary

The flag indicating whether the boundary integrator boundary() is to be used in the loop. Defaults to true.

Definition at line 102 of file local_integrator.h.

§ use_face

template<int dim, int spacedim = dim, typename number = double>

bool MeshWorker::LocalIntegrator< dim, spacedim, number >::use_face

The flag indicating whether the interior face integrator face() is to be used in the loop. Defaults to true.

Definition at line 108 of file local_integrator.h.

§ input_vector_names

template<int dim, int spacedim = dim, typename number = double>

std::vector<std::string> MeshWorker::LocalIntegrator< dim, spacedim, number >::input_vector_names

The names of the input vectors. If this vector is nonempty, it can be used by application programs to automatically select and verify the input vectors used for integration.

Note: This variable is currently not used by the library, but it is provided to help develop application programs.

Definition at line 118 of file local_integrator.h.

§ output_names

template<int dim, int spacedim = dim, typename number = double>

std::vector<std::string> MeshWorker::LocalIntegrator< dim, spacedim, number >::output_names

The names of the results produced. If this vector is nonempty, it can be used by application programs to automatically assign names to output values and/or verify the names of vectors.

Note: This variable is currently not used by the library, but it is provided to help develop application programs.
