virtual void BaseMeshReader::check_compatible_mesh ( Mesh & mesh )

pure virtual

Check if nodes and elements of reader mesh is compatible with mesh.

Implemented in VtkMeshReader, GmshMeshReader, and PvdMeshReader.

BaseMeshReader::DECLARE_EXCEPTION	(	ExcWrongFormat	,
		<< "Wrong format of "<< EI_Type::val<< "	,
		"<< EI_TokenizerMsg::val<< "\n"<< "in the input file:"<< EI_MeshFile::qval
	)

		<< "Unsupported extension "<< EI_FileExtension::qval<< " of the input file: "<< EI_MeshFile::qval
	)

		<< "No data for field: "<< EI_FieldName::qval<< " and time: "<< EI_Time::val<< " in the input file: "<< EI_MeshFile::qval
	)

BaseMeshReader::DECLARE_INPUT_EXCEPTION	(	ExcMissingFieldDiscretization	,
		<< "Missing data type specification for field: "<< EI_FieldName::qval<< " and time: "<< EI_Time::val<< " in the input file: "<< EI_MeshFile::qval<< "\	nPlease,
		add value of key 'input_discretization'."
	)

virtual MeshDataHeader& BaseMeshReader::find_header ( HeaderQuery & header_query )

pure virtual

Find data header for time and field given by header_query.

Implemented in VtkMeshReader, GmshMeshReader, and PvdMeshReader.

template<typename T >

ElementDataCache< T >::ComponentDataPtr BaseMeshReader::get_element_data	(	unsigned int	n_entities,
		unsigned int	n_components,
		bool	boundary_domain,
		unsigned int	component_idx
	)

Reads ElementData sections of opened mesh file. Method must be call after set_data_header method. If such section has not been yet read, we read the data section into raw buffer data. The buffer must have size at least n_components * n_entities. Indexes in the map must be smaller then n_entities.

Possible optimizations: If the map ID lookup seem slow, we may assume that IDs are in increasing order, use simple array of IDs instead of map and just check that they comes in in correct order.

Parameters

n_entities	count of entities (elements)
n_components	count of components (size of returned data is given by n_entities*n_components)
boundary_domain	flag determines that data is read for boundary or bulk elements
component_idx	component index of MultiField
