Detailed Description
class Dune::PDELab::DiscreteGridFunctionPiola< T, X >
DiscreteGridFunction with Piola transformation.
If a GridFunctionSpace with local-valued finite elements is used, this class can only be used for scalar functions, since for vector-valued local finite elements the values must be transformed, and the transformation depends on the type of element. For H(div) elements (Raviart-Thomas) look at DiscreteGridFunctionPiola.
If a GridFunctionSpace with finite elements using the new global-valued interface is used, this class can be used as-is even for vector-valued functions.
If you have a GridFunctionSpace tree of 1-component grid-function spaces, and want to collectively treat them as a vector-valued grid-function, look at VectorDiscreteGridFunction.
