class Dune::Vtk::DataCollectorInterface< GridViewType, Derived, Partition >
Base class for data collectors in a CRTP style.
- Template Parameters
-
GridViewType | Model of Dune::GridView |
Derived | Implementation of a concrete DataCollector. |
Partition | Dune::PartitionType [Partitions::InteriorBorder] |
template<class GridViewType , class Derived , class Partition = Partitions::InteriorBorder>
template<class T , class VtkFunction >
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)
template<class GridViewType , class Derived , class Partition = Partitions::InteriorBorder>
template<class T >
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
