Detailed Description

Collection of finite elements from the same family in multiple dimensions. This class is used to match the degrees of freedom of a FiniteElementSpace between elements, and to provide the finite element restriction from an element to its boundary.

void mfem::FiniteElementCollection::SubDofOrder ( int  Geom,
int  SDim,
int  Info,
Array< int > &  dofs 
) const

Get the local dofs for a given sub-manifold.

Return the local dofs for a SDim-dimensional sub-manifold (0D - vertex, 1D - edge, 2D - face) including those on its boundary. The local index of the sub-manifold (inside Geom) and its orientation are given by the parameter Info = 64 * SubIndex + SubOrientation. Naturally, it is assumed that 0 <= SDim <= Dim(Geom).

Reimplemented in mfem::L2_FECollection.
