Detailed Description

template<class GridView, int ORDER = -1>
class Dune::Vtk::DiscontinuousLagrangeDataCollector< GridView, ORDER >

Implementation of DataCollector for Lagrange cells.

In contrast to LagrangeDataCollector this one is discontinuous across cells and will create one copy per cell for each vertex. This DataCollector is particularly suited for writing higher order discontinuous polynomial 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 , int ORDER = -1>

Cells Dune::Vtk::DiscontinuousLagrangeDataCollector< GridView, ORDER >::cellsImpl ( ) const

inline

Return cell types, offsets, and connectivity.

Cells The cell connectivity is composed of cell vertices first and second cell edges, where the indices are grouped [vertex-indices..., (vertices)+edge-indices...]

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

pointsImpl()

template<class GridView , int ORDER = -1>

template<class T >

std::vector< T > Dune::Vtk::DiscontinuousLagrangeDataCollector< GridView, ORDER >::pointsImpl ( ) const

inline

Return a vector of point coordinates.

The vector of point coordinates is composed of vertex coordinates first and second edge center coordinates.
