Detailed Description

template<int dimension>
class Kaskade::GlobalBarycentricPermutation< dimension >

A class for computing permutations of local vertex numbers of simplex subentities to a globally unique ordering.

Use this to compute globally unique numberings of degrees of freedom, as necessary for global continuity of finite element functions.

template<int codim>

std::array< int, dimension+1-codim > Kaskade::GlobalBarycentricPermutation< dimension >::barycentricSubsetPermutation ( int  e ) const

inline

Computes a permutation of barycentric coordinates to globally unique ordering.

Template Parameters

codim

the codimension of the considered subentity

Parameters

e	the subentity number in the cell (among those of given codimension)

Returns

the index permutation vector \( \pi \)

If \( i \) is a barycentric coordinate direction according to the globally unique ordering, \( \pi(i) \) is its cell-local barycentric coordinate direction in the reference element.

A dynamic interface to barycentricSubsetPermutation.

Parameters

e	the subentity number in the cell (among those of given codimension)
codim	the codimension of the subentity
out	points to at least dimension+1-codim entries to be filled
