Constructor & Destructor Documentation

◆ XdrIO() [1/2]

libMesh::XdrIO::XdrIO	(	MeshBase &	,
		const bool	= `false`
	)

explicit

Constructor.

Takes a writable reference to a mesh object. This is the constructor required to read a mesh. The optional parameter binary can be used to switch between ASCII (false, the default) or binary (true) files.

◆ XdrIO() [2/2]

libMesh::XdrIO::XdrIO	(	const MeshBase &	,
		const bool	= `false`
	)

explicit

Constructor.

Takes a reference to a constant mesh object. This constructor will only allow us to write the mesh. The optional parameter binary can be used to switch between ASCII (false, the default) or binary (true) files.

◆ ~XdrIO()

virtual libMesh::XdrIO::~XdrIO ( )

◆ write_nodal_data() [2/2]

virtual void libMesh::MeshOutput< MeshBase >::write_nodal_data	(	const std::string &	,
		const NumericVector< Number > &	,
		const std::vector< std::string > &
	)

virtualinherited

This method should be overridden by "parallel" output formats for writing nodal data.

Instead of getting a localized copy of the nodal solution vector, it is passed a NumericVector of type=PARALLEL which is in node-major order i.e. (u0,v0,w0, u1,v1,w1, u2,v2,w2, u3,v3,w3, ...) and contains n_nodes*n_vars total entries. Then, it is up to the individual I/O class to extract the required solution values from this vector and write them in parallel.

If not implemented, localizes the parallel vector into a std::vector and calls the other version of this function.

Reimplemented in libMesh::Nemesis_IO.

This method implements writing a mesh with discontinuous data to a specified file where the nodal data and variables names are provided.
