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 >

int  ncomps = 1,
int  mycomp = 0 

construct from a vector and a name

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.
