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 171 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 179 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 187 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 200 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 236 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 144 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 154 of file output.h.
