template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

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

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

virtual AbstractTetrahedralElement< ELEMENT_DIM, SPACE_DIM >::~AbstractTetrahedralElement ( )

inlinevirtual

Virtual destructor, since this class has virtual methods.
