QuadraticMesh< DIM >::QuadraticMesh ( double  spaceStep,
double  width,
double  height = 0,
double  depth = 0 
) [inline]

Create a quadratic mesh on a slab (on a line in 1D, rectangle in 2d, cuboid in 3D), with the given widths and given spacestep. In 1D height and depth need to passed in as 0 (the default value), in 2D depth must be zero

Parameters:
spaceStep The spatial stepsize
width the width of the cuboid
height the height of the cuboid
depth the depth of the cuboid

template<unsigned DIM>
void QuadraticMesh< DIM >::AddNodeToBoundaryElement ( BoundaryElement< DIM-1, DIM > *  pBoundaryElement,
Element< DIM, DIM > *  pElement,
unsigned  internalNode 
) [inline, private]

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 element and adds it to the std::vector of boundary elements.

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 QuadraticMesh< DIM >::AddExtraBoundaryNodes ( BoundaryElement< DIM-1, DIM > *  pBoundaryElement,
Element< DIM, DIM > *  pElement,
unsigned  nodeIndexOppositeToFace 
) [inline, private]

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:
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

Element< DIM, DIM > *  pElement,
unsigned  node0,
unsigned  node1,
unsigned  node2,
unsigned &  rOffset,
bool &  rReverse 
) [inline, private]

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

unsigned  internalNode0,
unsigned  internalNode1,
unsigned  internalNode2,
unsigned  offset,
bool  reverse 
) [inline, private]

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:
document these parameters
Parameters:
pBoundaryElement 
pElement 
internalNode0 
internalNode1 
internalNode2 
offset 
reverse

template<unsigned DIM>
void QuadraticMesh< DIM >::ConstructLinearMesh ( unsigned  numElemX  )  [inline, private, virtual]

Create a quadratic mesh on the interval [0,numElemX] with numElemX elements in each direction. This is private, users should call ConstructRegularSlabMesh();

Parameters:
numElemX Number of elements in x-direction (also, the width of the final mesh)

template<unsigned DIM>
void QuadraticMesh< DIM >::ConstructRectangularMesh ( unsigned  numElemX,
unsigned  numElemY,
bool  unused = true 
) [inline, private, virtual]

Create a quadratic mesh on a rectangle from (0,0) to (numElemX,numElemY) with that number of elements in each direction. This writes a temporary node file and uses triangle to mesh this nodefile. The method overloads the equivalent method in AbstractTetrahedralMesh. This is private, users should call ConstructRegularSlabMesh();

Parameters:
numElemX Number of elements in x-direction (also, the width of the final mesh)
numElemY Number of elements in y-direction (also, the height of the final mesh)
unused (defaults to true; must always be true) is for compatibility of the interface of this method with same name in AbstractTetrahedralMesh.

template<unsigned DIM>
void QuadraticMesh< DIM >::ConstructCuboid ( unsigned  numElemX,
unsigned  numElemY,
unsigned  numElemZ 
) [inline, private, virtual]

Create a quadratic mesh on a cuobid from (0,0,0) to (numElemX,numElemY,numElemZ) with that number of elements in each direction. This writes a temporary node file and uses tetgen to mesh this nodefile. The method overloads the equivalent method in AbstractTetrahedralMesh. This is private, users should call ConstructRegularSlabMesh();

Parameters:
numElemX Number of elements in x-direction (also, the width of the final mesh)
numElemY Number of elements in y-direction (also, the height of the final mesh)
numElemZ Number of elements in y-direction (also, the depth of the final mesh)
