Detailed Description

template<typename T, typename X, std::size_t dimR = TypeTree::StaticDegree<T>::value>
class Dune::PDELab::VectorDiscreteGridFunction< T, X, dimR >

DiscreteGridFunction for vector-valued functions.

convert a power function space of scalar function spaces into a vector-valued grid function this is just an intermediate solution to provide VTK output

Template Parameters

T	Type of PowerGridFunctionSpace
X	Type of coefficients vector
dimR	Force a different number of components for the resulting GridFunction than the PowerGridFunctionSpace.
