Constructor & Destructor Documentation

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
AbstractTetrahedralElement< ELEMENT_DIM, SPACE_DIM >::AbstractTetrahedralElement ( unsigned  index,
const std::vector< Node< SPACE_DIM > * > &  rNodes 
) [inline]

Constructor which takes in a vector of nodes.

Parameters:
index the index of the element in the mesh
rNodes the nodes owned by the element

Definition at line 58 of file AbstractTetrahedralElement.cpp.

References AbstractTetrahedralElement< ELEMENT_DIM, SPACE_DIM >::CalculateJacobian(), and AbstractElement< ELEMENT_DIM, SPACE_DIM >::mNodes.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
AbstractTetrahedralElement< ELEMENT_DIM, SPACE_DIM >::AbstractTetrahedralElement ( unsigned  index = INDEX_IS_NOT_USED  )  [inline]

Default constructor, which doesn't fill in any nodes. The nodes must be added later.

Parameters:
index the index of the element in the mesh (defaults to INDEX_IS_NOT_USED)

Definition at line 93 of file AbstractTetrahedralElement.cpp.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
virtual AbstractTetrahedralElement< ELEMENT_DIM, SPACE_DIM >::~AbstractTetrahedralElement (  )  [inline, virtual]

Virtual destructor, since this class has virtual methods.

double AbstractTetrahedralElement< ELEMENT_DIM, SPACE_DIM >::GetVolume ( double  determinant  )  const [inline]

Get the volume of an element (or area in 2d, or length in 1d)

Parameters:
determinant a pre-calculated Jacobian determinant for this element.
Returns:
