Detailed Description

A class that, instead of assembling into a matrix or vector, outputs the results on a cell to a gnuplot patch.

This assembler expects that LocalResults contains quadrature values set with LocalResults::quadrature_value(). When it is initialized with the number of quadrature points in a single (!) space direction and the number of data fields to be displayed, it initializes LocalResults automatically. The number of data fields in local results will be increased by dim in order to accommodate for the coordinates of the data points.

While data slots for the space coordinates are allocated automatically, these coordinates are not entered. It is up to the user to enter the coordinates in the first dim data entries at every point. This adds the flexibility to output transformed coordinates or even something completely different.

Note
In the current implementation, only cell data can be written.

Member Function Documentation

◆ initialize()

void MeshWorker::Assembler::GnuplotPatch::initialize ( const unsigned int  n_points,
const unsigned int  n_vectors 
)
inline

Initialize for writing n data vectors. The number of points is the number of quadrature points in a single direction in a tensor product formula. It must match the number in the actual Quadrature used to create the patches. The total number of data vectors produced is n+dim and the first dim should be the space coordinates of the points. Nevertheless, it is up to the user to set these values to whatever is desired.

Definition at line 172 of file output.h.

◆ initialize_stream()

void MeshWorker::Assembler::GnuplotPatch::initialize_stream ( std::ostream &  stream)
inline

Set the stream os to which data is written. If no stream is selected with this function, data goes to deallog.

Definition at line 180 of file output.h.

◆ initialize_info()

template<int dim>
void MeshWorker::Assembler::GnuplotPatch::initialize_info ( DoFInfo< dim > &  info,
bool  face 
)
inline

Initialize the local data in the DoFInfo object used later for assembling.

The info object refers to a cell if !face, or else to an interior or boundary face.

Definition at line 188 of file output.h.

◆ assemble() [1/2]

template<int dim>
void MeshWorker::Assembler::GnuplotPatch::assemble ( const DoFInfo< dim > &  info)
inline

Write the patch to the output stream.

Definition at line 201 of file output.h.

◆ assemble() [2/2]

template<int dim>
void MeshWorker::Assembler::GnuplotPatch::assemble ( const DoFInfo< dim > &  info1,
const DoFInfo< dim > &  info2 
)
inline
Warning
Not implemented yet

Definition at line 237 of file output.h.

◆ write()

template<typename T >
void MeshWorker::Assembler::GnuplotPatch::write ( const T &  t) const
inlineprivate

Write the object T either to the stream os, if initialize_stream() has been called, or to deallog if no pointer has been set.

Definition at line 145 of file output.h.

◆ write_endl()

void MeshWorker::Assembler::GnuplotPatch::write_endl ( ) const
inlineprivate

Write an end-of-line marker either to the stream os, if initialize_stream has been called, or to deallog if no pointer has been set.

Definition at line 155 of file output.h.

Member Data Documentation

unsigned int MeshWorker::Assembler::GnuplotPatch::n_points
private

The number of points in one direction.

Definition at line 133 of file output.h.
