Constructor & Destructor Documentation

Tetrahedron3d()

concepts::Tetrahedron3d::Tetrahedron3d	(	Tetrahedron &	cntr,
		const MapTetrahedron3d &	map
	)

Constructor. Takes the connector cntr and the element map map and creates a cell.

Parameters

cntr	Topological information of the tetrahedron
map	Element map of the tetrahedron

Member Function Documentation

center()

Real3d concepts::Tetrahedron3d::center ( ) const

inlinevirtual

Returns the center of the cell.

Implements concepts::Cell3.

Definition at line 111 of file cell3D.hh.

chi()

Real3d concepts::Tetrahedron3d::chi	(	Real	xi,
		Real	eta,
		Real	zeta
	)		const

The element map. Maps a point from the unit cube $[0,1]^3$ onto the element.

Returns

Point in 3D in physical coordinates.

Parameters

xi
eta
zeta

child() [1/2]

virtual Tetrahedron3d * concepts::Tetrahedron3d::child ( uint  i )

virtual

Returns a pointer to the ith child. Children are created if they do not already exist.

Implements concepts::Cell3.

child() [2/2]

virtual const Tetrahedron3d * concepts::Tetrahedron3d::child ( uint  i ) const

virtual

Returns a pointer to the ith child. Children are not created if they do not already exist, instead 0 is returned.

Implements concepts::Cell3.

connector()

Tetrahedron & concepts::Tetrahedron3d::connector ( ) const

inlinevirtual

Returns the connector.

Implements concepts::Cell3.

Definition at line 100 of file cell3D.hh.

elemMap() [1/3]

virtual Real3d concepts::Cell::elemMap ( const Real  coord_local ) const

virtualinherited

Element map from point local coordinates in 1D.

Reimplemented in concepts::SphericalSurface3d, concepts::Sphere3d, concepts::Edge1d, and concepts::Edge2d.

elemMap() [2/3]

virtual Real3d concepts::Cell::elemMap ( const Real2d &  coord_local ) const

virtualinherited

Element map from point local coordinates in 2D.

Reimplemented in concepts::Triangle2d, concepts::Quad2d, concepts::InfiniteRect2d, concepts::Triangle3d, concepts::Quad3d, concepts::Cell2, concepts::SphericalSurface3d, concepts::Sphere3d, concepts::Edge1d, and concepts::Edge2d.

elemMap() [3/3]

virtual Real3d concepts::Cell::elemMap ( const Real3d &  coord_local ) const

virtualinherited

Element map from point local coordinates in 3D.

Reimplemented in concepts::Cell2, concepts::Hexahedron3d, concepts::SphericalSurface3d, concepts::Sphere3d, concepts::Edge1d, and concepts::Edge2d.

hasChildren()

bool concepts::Cell::hasChildren ( ) const

inlineinherited

Returns true if there is a least one child.

Definition at line 50 of file cell.hh.

info()

virtual std::ostream & concepts::Tetrahedron3d::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Implements concepts::Cell.

vertex()

Real3d concepts::Tetrahedron3d::vertex ( uint  i ) const

virtual

Returns the coordinates of the ith vertex.

Implements concepts::Cell3.
