Description

Contains functionality for L2-projections from one function space into another, which can live both on the same or different grids of potentially different dimensionality.

Note

In the case of the function space bases living on the same grid an optimized implementation could be implemented. Currently, we require a glue object containing the intersections between two grids to be provided to the free factory functions.

Classes
class	Dumux::Projector< ScalarType >
	Does an L2-projection from one discrete function space into another. The convenience functions makeProjectorPair or makeProjector can be used to create such a projection. More...
struct	Dumux::Projector< ScalarType >::Params
	Parameters that can be passed to project() More...
class	Dumux::ProjectorTraits< FEBasisDomain, FEBasisTarget >
	Traits class stating the type of projector between to bases. More...

Namespaces
namespace	Dumux
	make the local view function available whenever we use the grid geometry

Functions
template<class FEBasisDomain , class FEBasisTarget , class GlueType >
auto	Dumux::makeProjectorPair (const FEBasisDomain &feBasisDomain, const FEBasisTarget &feBasisTarget, GlueType glue)
	Creates a pair of projectors between the space with basis feBasisDomain to the space with basis feBasisTarget. More...
template<class FEBasisDomain , class FEBasisTarget , class GlueType >
auto	Dumux::makeProjector (const FEBasisDomain &feBasisDomain, const FEBasisTarget &feBasisTarget, GlueType glue)
	Creates a forward projector from the space feBasisDomain to the space with basis feBasisTarget. More...
template<class FEBasisDomain , class FEBasisTarget , class GlueType >
auto	Dumux::makeProjectionMatricesPair (const FEBasisDomain &feBasisDomain, const FEBasisTarget &feBasisTarget, GlueType glue)
	Creates the matrices underlying l2-projections. More...
template<class FEBasisDomain , class FEBasisTarget , class GlueType >
auto	Dumux::makeProjectionMatrices (const FEBasisDomain &feBasisDomain, const FEBasisTarget &feBasisTarget, GlueType glue)
	Creates the matrices underlying l2-projections. More...
