assemble_prolongation_matrix()

template<typename TDomain , typename TAlgebra , typename TElem >

void ug::Electromagnetism::NedelecProlongationMatrixHelper< TDomain, TAlgebra, TElem >::assemble_prolongation_matrix ( const domain_type &  domain, const DoFDistribution &  coarseDD, const DoFDistribution &  fineDD, matrix_type &  mat, std::vector< bool > &  vIsRestricted  )

assembles the prolongation matrix for one type of the grid elements

Assembles the prolongation matrix for the DoFs between the edges for one type of the grid elements. (This instantiation assumes that the dimensionality of the element is greater than 1.) To get the total prolongation matrix, the functions for all the types should be called.

Parameters

[in]	domain	the domain
[in]	coarseDD	the coarse grid DD
[in]	fineDD	the fine grid DD
[out]	mat	the interpolation matrix
[out]	vIsRestricted	whether a coarse grid DoF has children

GetRegularLocalCoordinate()

template<typename TDomain , typename TAlgebra , typename TElem >

void ug::Electromagnetism::NedelecProlongationMatrixHelper< TDomain, TAlgebra, TElem >::GetRegularLocalCoordinate ( const MultiGrid *  mg, Vertex *  v, TElem *  base, MathVector< TElem::dim > &  local  )

computes the local coordinates of a vertex according to the assumption of the regular refinement

Computes the local coordinates of a vertex according to the assumption of the regular refinement. The local coordinates are computed w.r.t. a given basis element that should be associated with the parent of the vertex whose all corners must be corners of the base element. (Otherwise an exception is thrown.) The vector of the local coordinates of the given vertex is the arithmetical average of the vectors of the local coordinates of its parent w.r.t. the base element.

Acknowledgements to S. Reiter.

Parameters

[in]	mg	the grid hierarchy
[in]	v	the vertex
[in]	base	the base element (for the local coordinates)
[out]	local	to save the local coordinates
