◆ addCellData()

template<class GV , class DC >

template<class Function , class... Args>

VtkWriterInterface & Dune::VtkWriterInterface< GV, DC >::addCellData	(	Function &&	fct,
		Args &&...	args
	)

inlineinherited

Attach cell data to the writer.

Attach a global function to the writer that will be evaluated at cell centers. The global function must be assignable to the function wrapper Vtk::Function. Additional argument for output datatype and number of components can be passed. See Vtk::Function Constructor for possible arguments.

Parameters

fct	A GridFunction, LocalFunction, or Dune::VTKFunction
args...	Additional arguments, like `name`, `numComponents`, `dataType` or `Vtk::FieldInfo`

◆ addPointData()

template<class GV , class DC >

template<class Function , class... Args>

VtkWriterInterface & Dune::VtkWriterInterface< GV, DC >::addPointData	(	Function &&	fct,
		Args &&...	args
	)

inlineinherited

Attach point data to the writer.

Attach a global function to the writer that will be evaluated at grid points (vertices and higher order points). The global function must be assignable to the function wrapper Vtk::Function. Additional argument for output datatype and number of components can be passed. See Vtk::Function Constructor for possible arguments.

Parameters

fct	A GridFunction, LocalFunction, or Dune::VTKFunction
args...	Additional arguments, like `name`, `numComponents`, `dataType` or `Vtk::FieldInfo`
