Detailed Description

template<typename GV, typename V>
class Dune::P0VTKFunction< GV, V >

Take a vector and interpret it as cell data for the VTKWriter.

This class turns a generic vector containing cell data into a VTKFunction. The vector must allow read access to the data via operator[]() and store the data in the order given by MultipleCodimMultipleGeomTypeMapper with a layout class that allows only elements. Also, it must support the method size().

While the number of components of the function is always 1, the vector may represent a field with multiple components of which one may be selected.

Template Parameters
GVType of GridView the vector applies to.
VType of vector.

◆ P0VTKFunction()

template<typename GV , typename V >
Dune::P0VTKFunction< GV, V >::P0VTKFunction ( const GV &  gv,
const V &  v_,
const std::string &  s_,
int  ncomps = 1,

VTK::Precision  prec = VTK::Precision::float32 
)
inline

construct from a vector and a name

Parameters
gvGridView to operate on (used to instantiate a MultipleCodimMultipleGeomeTypeMapper, otherwise no reference or copy is stored). Note that this must be the GridView the vector applies to as well as the GridView later used by the VTKWriter – i.e. we do not implicitly restrict or prolongate the data.
v_Reference to the vector holding the data. The reference is stored internally and must be valid for as long as this functions evaluate method is used.
s_Name of this function in the VTK file.
ncompsNumber of components of the field represented by the vector.
mycompNumber of the field component this function is responsible for.
precthe precision with which to output the field
