Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
class VertexElement< ELEMENT_DIM, SPACE_DIM >

An element class for use in the VertexMesh class. The main difference between this and the Element class is that a VertexElement can have a variable number of nodes associated with it.

Definition at line 44 of file VertexElement.hpp.

) [inline]

Constructor.

Parameters:
index global index of the element

rFaces vector of faces associated with the element
rOrientations vector of orientations of the faces associated with the element

template<class Archive>
void VertexElement< ELEMENT_DIM, SPACE_DIM >::serialize ( Archive &  archive,
const unsigned int  version 
) [inline, private]

Note that serialization of the mesh and cells is handled by load/save_construct_data.

Note also that member data related to writers is not saved - output must be set up again by the caller after a restart.

Parameters:
archive the archive
version the current version of this class

Faces of the VertexElement, which should be distinct.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
std::vector<bool> VertexElement< ELEMENT_DIM, SPACE_DIM >::mOrientations [private]

How each face is oriented. From the perspective of the centre of the element, the vertices of each face should be ordered anti clockwise. If and only if this is false, the order of vertices in the corresponding face should be reversed.

N.B. Most faces belong to two elements, but with opposite orientations. This allows us to reuse the face data across the two cells.
