Detailed Description

template<class GridView, class Partition = Partitions::InteriorBorder>
class Dune::Vtk::ContinuousDataCollector< GridView, Partition >

Implementation of DataCollector for linear cells, with continuous data.

Member Function Documentation

cellData()

std::vector< T > Dune::Vtk::DataCollectorInterface< GridView , Derived, Partitions::InteriorBorder >::cellData ( VtkFunction const &  fct ) const

inlineinherited

Return a flat vector of function values evaluated at the cells in the order of traversal.

See also

pointData. Note: Cells might be described explicitly by connectivity, offsets, and types, e.g. in an UnstructuredGrid, or might be described implicitly by the grid type, e.g. in StructuredGrid.

cells()

template<class GridView , class Derived , class Partition = Partitions::InteriorBorder>

Cells Dune::Vtk::UnstructuredDataCollectorInterface< GridView, Derived, Partition >::cells ( ) const

inlineinherited

Return cell types, offsets, and connectivity.

Cells

cellsImpl()

template<class GridView , class Partition = Partitions::InteriorBorder>

Cells Dune::Vtk::ContinuousDataCollector< GridView, Partition >::cellsImpl ( ) const

inline

Return the types, offsets and connectivity of the cells, using the same connectivity as given by the grid.

pointData()

std::vector< T > Dune::Vtk::DataCollectorInterface< GridView , Derived, Partitions::InteriorBorder >::pointData ( VtkFunction const &  fct ) const

inlineinherited

Return a flat vector of function values evaluated at the points.

In case of a vector valued function, flat the vector entries: [fct(p0)_0, fct(p0)_1, fct(p0)_2, fct(p1)_0, ...] where the vector dimension must be 3 (possible extended by 0s) In case of tensor valued function, flat the tensor row-wise: [fct(p0)_00, fct(p0)_01, fct(p0)_02, fct(p0)_10, fct(p0)_11, fct(p0)_12, fct(p0)_20...] where the tensor dimension must be 3x3 (possible extended by 0s)

points()

std::vector< T > Dune::Vtk::DataCollectorInterface< GridView , Derived, Partitions::InteriorBorder >::points ( ) const

inlineinherited

Return a flat vector of point coordinates.

All coordinates are extended to 3 components and concatenated. [p0_x, p0_y, p0_z, p1_x, p1_y, p1_z, ...] If the GridView::dimensionworld < 3, the remaining components are set to 0
