void QuadraticMeshHelper< DIM >::AddExtraBoundaryNodes ( AbstractTetrahedralMesh< DIM, DIM > *  pMesh, BoundaryElement< DIM-1, DIM > *  pBoundaryElement, Element< DIM, DIM > *  pElement, unsigned  nodeIndexOppositeToFace  )

static

Given a face in an element (defined by giving an element and the opposite node number to the face) that corresponds to a given boundary element, this method adds in the face's internal nodes to the boundary element (in the correct order).

Parameters

pMesh	the (quadratic) mesh to modify
pBoundaryElement	pointer to a boundary element in the mesh
pElement	pointer to an element in the mesh
nodeIndexOppositeToFace	index of a node in the mesh

template<unsigned DIM>

void QuadraticMeshHelper< DIM >::AddInternalNodesToBoundaryElements ( AbstractTetrahedralMesh< DIM, DIM > *  pMesh, AbstractMeshReader< DIM, DIM > *  pMeshReader  )

static

Top level method for adding internal nodes to the mesh's boundary elements.

Note that the internal nodes must already exist in the mesh; this method just associates them with the relevant boundary elements. If the mesh on disk has internal node indices in the boundary elements file, then we just look them up. Otherwise we figure out which normal element has each boundary element as a face, and extract the internal nodes from that.

Parameters

pMesh	the mesh to modify
pMeshReader	pointer to the reader for accessing the on-disk mesh data

template<unsigned DIM>

void QuadraticMeshHelper< DIM >::AddNodesToBoundaryElements ( AbstractTetrahedralMesh< DIM, DIM > *  pMesh, AbstractMeshReader< DIM, DIM > *  pMeshReader  )

static

Used by AddInternalNodesToBoundaryElements in the case where the on-disk mesh doesn't have the associations already, and by the linear -> quadratic mesh conversion routines.

If there is an on-mesh disk that has containing element information in its edge/face file, then this can be supplied to speed up finding the full element containing each boundary element.

Parameters

pMesh	the mesh to modify
pMeshReader	pointer to the reader for accessing the on-disk mesh data, if any; NULL otherwise

Todo:

#1930 Until there is an interator_facade over boundary elements,

Todo:

#1930 Once there is an interator_facade then we can do: elem_index = pMeshReader->GetFaceData(face_index).ContainingElement;

This method adds the given node (defined by an element and a node index) to the given boundary element, and also sets the node as a boundary node and adds it to the mesh's boundary nodes.

Parameters

pBoundaryElement	pointer to a boundary element in the mesh
pElement	pointer to an element in the mesh
internalNode	index of a node in the mesh

void QuadraticMeshHelper< DIM >::HelperMethod1 ( unsigned  boundaryElemNode0, unsigned  boundaryElemNode1, Element< DIM, DIM > *  pElement, unsigned  node0, unsigned  node1, unsigned  node2, unsigned &  rOffset, bool &  rReverse  )

static

Nasty helper method for AddNodeToBoundaryElement() in 3D.

This method takes in the three vertices of a face which match the given boundary element, and figure out if the order of the nodes in the face is reversed in the boundary element (returned in the bool 'rReverse'). Also, the offset between the first node in the face (as given to this method) and the first node in the boundary element is computed (returned in the variable 'rOffset'). Offset should then be applied before reverse to match the face nodes to the boundary element nodes.

Todo:

document these parameters

Parameters

boundaryElemNode0
boundaryElemNode1
pElement
node0
node1
node2
rOffset
rReverse

static

Nasty helper method for AddNodeToBoundaryElement() in 3D.

This method takes the three internal nodes for some face in some element, applies the given offset and reverse (see HelperMethod1) to them, to get the ordered internal nodes which should given to the boundary element. It then calls AddNodeToBoundaryElement with each of the three internal nodes.

Todo:

Parameters

pMesh
pBoundaryElement
pElement
internalNode0
internalNode1
internalNode2
offset
reverse
