Detailed Description

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

A concrete element class which inherits from AbstractTetrahedralElement.

Definition at line 46 of file Element.hpp.

Constructor & Destructor Documentation

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
Element< ELEMENT_DIM, SPACE_DIM >::Element ( unsigned  index,
std::vector< Node< SPACE_DIM > * >  nodes 
) [inline]

Constructor which takes in a vector of nodes.

Parameters:
index the index of the element in the mesh
nodes the nodes owned by the element
Todo:
make rNodes like in AbstractTetrahedralElement? (#991)

Definition at line 42 of file Element.cpp.

References Element< ELEMENT_DIM, SPACE_DIM >::RegisterWithNodes().

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
Element< ELEMENT_DIM, SPACE_DIM >::Element ( const Element< ELEMENT_DIM, SPACE_DIM > &  rElement,
const unsigned  index 
) [inline]

Copy constructor which allows a new index to be specified.

Todo:
this is rather dubious; a factory method might be better.
Parameters:
rElement an element to copy
index the index of the new element

void Element< ELEMENT_DIM, SPACE_DIM >::UpdateNode ( const unsigned &  rIndex,
Node< SPACE_DIM > *  pNode 
) [inline, virtual]

Update node at the given index.

Parameters:
rIndex is an local index to which node to change
pNode is a pointer to the replacement node
Update node at the given index
Parameters:
rIndex is an local index to which node to change
pNode is a pointer to the replacement node

void Element< ELEMENT_DIM, SPACE_DIM >::ResetIndex ( unsigned  index  )  [inline]

Reset the index of this boundary element in the mesh.

Parameters:
index the new index of the boundary element

c_matrix< double, ELEMENT_DIM, SPACE_DIM > &  rInverseJacobian 
) [inline]

Calculate the circumsphere/circumcircle of this element.

Returns:
a vector containing x_centre, y_centre,...,radius^2 Calculate the circumsphere/circumcircle of this element.
After reconstructing a cylindrical 2d mesh, the jacobian data of the periodic elements is not valid anymore. We want to use the jacobians computed before swapping the nodes.

Returns:
a vector containing x_centre, y_centre,...,radius^2
Parameters:
rJacobian the Jacobian matrix
rInverseJacobian the inverse Jacobian matrix

double Element< ELEMENT_DIM, SPACE_DIM >::CalculateCircumsphereVolume (  ) 

Get the volume of the circumsphere, or area of the circumcircle, of this element.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
double Element< ELEMENT_DIM, SPACE_DIM >::CalculateQuality (  )  [inline]

The quality of a triangle/tetrahedron is the ratio between the volume of the shape and the volume of its circumsphere. This is normalised by dividing through by the Platonic ratio.

Calculate the interpolation weights, but if we are not within the element (one or more negative weights), we project onto the element, rather than extrapolating from it.

Parameters:
testPoint the point
