Size calculation

The FiniteElementMap provides different methods to compute the size of the GridFunctionSpace (if possible) without iterating the grid. The approach is as follows (pseudo code):

computeNumberOfDofs(GridView, FEM):
if(FEM.fixedSize()):
sum(FEM.size(gt)*GridView.size(gt) for gt in GeometryTypes)
else
sum(FEM.find(E).basis().size() for E in GridView.entities<0>())
Dune::GridView
Grid view abstract base class.
Definition: gridview.hh:66
Dune::PDELab::SimpleLocalFiniteElementMap< Dune::P0LocalFiniteElement< D, R, d >, d >::find
const Traits::FiniteElementType & find(const EntityType &e) const
get local basis functions for entity
Definition: finiteelementmap.hh:116
Dune::FloatCmp::gt
bool gt(const T &first, const T &second, typename EpsilonType< T >::Type epsilon)
test if first greater than second
Definition: float_cmp.cc:158
static constexpr std::size_t size (GeometryType gt)=delete
 if the FiniteElementMap is fixedSize, the size methods computes the number of DOFs for given GeometryType.
