Dumux::Projector< ScalarType > Class Template Reference

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.

	Projector (Matrix &&massMatrix, Matrix &&projectionMatrix)
	Constructor. Receives the mass and projection matrix that define the linear system describing the L2-projection from a function space into another. More...
	Projector (Matrix &&massMatrix, Matrix &&projectionMatrix, std::vector< std::size_t > &&indexMap, std::size_t numDofsTarget)
	Constructor for projection into a target space that occupies a larger geometric region than the domain space. In this case, the mass matrix can be chosen such that is is solved for only those dofs which will be populated with values from the projection. This requires an additional index map that maps the entries of the projected solution into the solution vector for the target space. Furthermore, the number of degrees of freedom must be specified to set up the coefficient vector with correct size for the target space. More...
