Detailed Description

template<class GridView>
class Dune::SubsamplingVTKWriter< GridView >

Writer for the ouput of subsampled grid functions in the vtk format.

Writes arbitrary grid functions (living on cells or vertices of a grid) to a file suitable for easy visualization with The Visualization Toolkit (VTK). In contrast to the regular VTKWriter, this Writer allows subsampling of the elements via VirtualRefinement. The SubSamplingVTKWriter always writes nonconforming data.

Constructor & Destructor Documentation

template<class GridView >
Dune::SubsamplingVTKWriter< GridView >::SubsamplingVTKWriter ( const GridView gridView,
unsigned int  level_,
bool  coerceToSimplex_ = false 
) [inline, explicit]

Construct a SubsamplingVTKWriter working on a specific GridView.

Parameters:
gridView The gridView the grid functions live on. (E. g. a LevelGridView.)
level_ The level for the subrefinement.
coerceToSimplex_ Set this to true to always triangulate elements into simplices, even where it's not necessary (i.e. for hypercubes).

The datamode is always nonconforming.


Member Function Documentation

template<class GridView>
void Dune::VTKWriter< GridView >::addCellData ( const VTKFunctionPtr p  )  [inline, inherited]

Add a grid function that lives on the cells of the grid to the visualization.

Parameters:
p Dune::shared_ptr to the function to visualize
template<class GridView>
void Dune::VTKWriter< GridView >::addCellData ( VTKFunction p  )  [inline, inherited]

Add a grid function that lives on the cells of the grid to the visualization.

Parameters:
p The function to visualize. The VTKWriter object will take ownership of the VTKFunction *p and delete it when it's done.
template<class GridView>
template<class V >
void Dune::VTKWriter< GridView >::addCellData ( const V &  v,
const std::string &  name,
int  ncomps = 1 
) [inline, inherited]

Add a grid function (represented by container) that lives on the cells of the grid to the visualization.

The container has to have random access via operator[] (e. g. std::vector). The value of the grid function for an arbitrary element will be accessed by calling operator[] with the index (corresponding with the grid view) of the element. For vector valued data all components for an element are assumed to be consecutive.

Parameters:
v The container with the values of the grid function for each cell.
name A name to identify the grid function.
ncomps Number of components (default is 1).
template<class GridView>
void Dune::VTKWriter< GridView >::addVertexData ( const VTKFunctionPtr p  )  [inline, inherited]

Add a grid function that lives on the vertices of the grid to the visualization.

Parameters:
p Dune::shared_ptr to the function to visualize
template<class GridView>
void Dune::VTKWriter< GridView >::addVertexData ( VTKFunction p  )  [inline, inherited]

Add a grid function that lives on the vertices of the grid to the visualization.

Parameters:
p The function to visualize. The VTKWriter object will take ownership of the VTKFunction *p and delete it when it's done.

return name of a parallel header file

Parameters:
name Base name of the VTK output. This should be without any directory parts and without a filename extension.
path Directory part of the resulting header name. May be empty, in which case the resulting name will not have a directory part. If non-empty, may or may not have a trailing '/'. If a trailing slash is missing, one is appended implicitly.
commSize Number of processes writing a parallel vtk output.

std::string Dune::VTKWriter< GridView >::getParallelPieceName ( const std::string &  name,

) const [inline, protected, inherited]

return name of a parallel piece file

Parameters:
name Base name of the VTK output. This should be without any directory parts and without a filename extension.
path Directory part of the resulting piece name. May be empty, in which case the resulting name will not have a directory part. If non-empty, may or may not have a trailing '/'. If a trailing slash is missing, one is appended implicitly.
commRank Rank of the process to generate a piece name for.
commSize Number of processes writing a parallel vtk output.

template<class GridView>
std::string Dune::VTKWriter< GridView >::getSerialPieceName ( const std::string &  name,
const std::string &  path 
) const [inline, protected, inherited]

return name of a serial piece file

This is similar to getParallelPieceName, but skips the prefixes for commSize ("s####:") and commRank ("p####:").

Parameters:
name Base name of the VTK output. This should be without any directory parts and without a filename extension.
path Directory part of the resulting piece name. May be empty, in which case the resulting name will not have a directory part. If non-empty, may or may not have a trailing '/'. If a trailing slash is missing, one is appended implicitly.

VTK::OutputType  type = VTK::ascii 
) [inline, inherited]

write output (interface might change later)

"pwrite" means "path write" (i.e. write somewhere else than the current directory). The "p" does not mean this method has a monopoly on parallel writing, the regular write(const std::string &, VTK::OutputType) method can do that just fine.

Parameters:
name Base name of the output files. This should not contain any directory part and not filename extensions. It will be used both for each processes piece as well as the parallel collection file.
path Directory where to put the parallel collection (.pvtu/.pvtp) file. If it is relative, it is taken realtive to the current directory.
extendpath Directory where to put the piece file (.vtu/.vtp) of this process. If it is relative, it is taken relative to the directory denoted by path.
type How to encode the data in the file.
Note:
Currently, extendpath may not be absolute unless path is absolute, because that would require the value of the current directory.
Exceptions:
NotImplemented Extendpath is absolute but path is relative.
IOError Failed to open a file.

Parameters:

commRank Rank of the current process.
commSize Number of processes taking part in this write operation.

std::string Dune::VTKWriter< GridView >::write ( const std::string &  name,
VTK::OutputType  type = VTK::ascii 
) [inline, inherited]

write output (interface might change later)

This method can be used in parallel as well as in serial programs. For serial runs (commSize=1) it chooses other names without the "s####:p####:" prefix for the .vtu/.vtp files and omits writing of the .pvtu/pvtp file however. For parallel runs (commSize > 1) it is the same as a call to pwrite() with path="" and extendpath="".

Parameters:
[in] name basic name to write (may not contain a path)
[in] type type of output (e.g,, ASCII) (optional)
