void VtkMeshWriter< ELEMENT_DIM, SPACE_DIM >::AddCellData	(	std::string	name,
		std::vector< c_vector< double, SPACE_DIM > >	data
	)			`[inline]`

Add a vector data field to each element (known as "cell" in VTK).

Parameters:

	name	is a meaningful name with which to annotate the data
	data	is the data which should appear in the same order as the element numbering The length of the data vector is assumed to match the number of elements in the mesh. Checking cannot be done at this stage since the data is associated with an empty VTK mesh structure.

Add a scalar data field to each element (known as "cell" in VTK).

Parameters:

	name	is a meaningful name with which to annotate the data
	data	is the data which should appear in the same order as the element numbering The length of the data vector is assumed to match the number of elements in the mesh. Checking cannot be done at this stage since the data is associated with an empty VTK mesh structure.

Add a vector data field to each node (known as "point" in VTK).

Parameters:

	name	is a meaningful name with which to annotate the data
	data	is the data which should appear in the same order as the node numbering The length of the data vector is assumed to match the number of nodes in the mesh Checking cannot be done at this stage since the data is associated with an empty VTK mesh structure.

void VtkMeshWriter< ELEMENT_DIM, SPACE_DIM >::AddProvenance ( std::string fileName ) [inline]

Add Chaste provenance data to a VTK file as an XML comment string

Parameters:

fileName

is the file name relative to mpOutputFileHandler The file is assumed have been written to and to be closed - so that it can safely be appended to.

Parameters:

rMesh

the mesh (must be a DistributedTetrahedralMesh)

void VtkMeshWriter< ELEMENT_DIM, SPACE_DIM >::WriteFiles ( ) [inline, virtual]

		bool	keepOriginalElementIndexing = `true`
	)			`[inline, virtual]`

Write files. Overrides the method implemented in AbstractTetrahedralMeshWriter, which concentrates mesh data onto a single file in order to output a monolithic file. For VTK, a DistributedTetrahedralMesh in parallel is instead written out as a set of .vtu files (one for each sub-mesh) and a .pvtu file that provides the visualizer with information about them.

Parameters:

	rMesh	the mesh
	keepOriginalElementIndexing	Whether to write the mesh with the same element ordering. Optimisations can be applied if this is not needed.
