virtual bool Bempp::GridView::containsEntity ( const Entity< 0 > & e ) const

pure virtual

True if the entity e of codimension 0 is contained in this grid view.

Note: If e is not an element of the grid, then the result of containsEntity() is undefined.

Implemented in Bempp::ConcreteGridView< DuneGridView >.

virtual bool Bempp::GridView::containsEntity ( const Entity< 1 > & e ) const

pure virtual

True if the entity e of codimension 1 is contained in this grid view.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Implemented in Bempp::ConcreteGridView< DuneGridView >.

virtual bool Bempp::GridView::containsEntity ( const Entity< 2 > & e ) const

pure virtual

True if the entity e of codimension 2 is contained in this grid view.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Implemented in Bempp::ConcreteGridView< DuneGridView >.

virtual bool Bempp::GridView::containsEntity ( const Entity< 3 > & e ) const

pure virtual

True if the entity e of codimension 3 is contained in this grid view.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Implemented in Bempp::ConcreteGridView< DuneGridView >.

void Bempp::GridView::getRawElementData	(	arma::Mat< float > &	vertices,
		arma::Mat< int > &	elementCorners,
		arma::Mat< char > &	auxData
	)		const

inline

Get raw data describing the geometry of all codim-0 entities contained in this grid view.

Parameters

[out]	vertices	On output, a 2D array whose (i,j)th element is the ith coordinate of the vertex of index j.
[out]	elementCorners	On output, a 2D array whose (i,j)th element is the index of the ith corner of jth codim-0 entity, or -1 if this entity has less than i-1 corners.
[out]	auxData	Auxiliary data, to be used in future to describe the geometry of curvilinear elements. Currently this argument is always set to an empty matrix.This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

void Bempp::GridView::getRawElementData	(	arma::Mat< double > &	vertices,
		arma::Mat< int > &	elementCorners,
		arma::Mat< char > &	auxData
	)		const

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

void Bempp::GridView::getRawElementData	(	arma::Mat< double > &	vertices,
		arma::Mat< int > &	elementCorners,
		arma::Mat< char > &	auxData,
		std::vector< int > &	domainIndices
	)		const

inline

Get raw data describing the geometry of all codim-0 entities contained in this grid view.

This overload takes an additional argument, domainIndices, which on output contains indices of the grid domains to which the corresponding elements from elementCorners belong.

void Bempp::GridView::getRawElementData	(	arma::Mat< float > &	vertices,
		arma::Mat< int > &	elementCorners,
		arma::Mat< char > &	auxData,
		std::vector< int > &	domainIndices
	)		const

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

virtual const ReverseElementMapper& Bempp::GridView::reverseElementMapper ( ) const

pure virtual

Mapping from codim-0 entity index to entity pointer.

Note that this object is not updated when the grid is adapted. In that case you need to create a new grid view and obtain a new reference to the reverse element mapper.

Implemented in Bempp::ConcreteGridView< DuneGridView >.

virtual std::auto_ptr<VtkWriter> Bempp::GridView::vtkWriter ( Dune::VTK::DataMode dm = Dune::VTK::conforming ) const

pure virtual

Create a VtkWriter for this grid view.

Parameters

dm	Data mode (conforming or nonconforming; see the documentation of Dune::VTK::DataMode for details).

Implemented in Bempp::ConcreteGridView< DuneGridView >.
