Constructor & Destructor Documentation

Triangle3d()

concepts::Triangle3d::Triangle3d	(	Triangle &	cntr,
		const MapTriangle3d &	map
	)

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

Parameters

cntr	Topological information of the triangle
map	Element map of this triangle

Member Function Documentation

center()

Real3d concepts::Triangle3d::center ( ) const

inlinevirtual

Returns the center of the cell.

Implements concepts::Cell2.

Definition at line 795 of file cell2D.hh.

chi()

Real3d concepts::Triangle3d::chi	(	Real	xi,
		Real	eta
	)		const

The element map. Maps a corner from the unit square [0,1]² onto the element. The three vertices are (0, 0), (1, 0) and (1, 1).

Returns

Point in 3D in physical coordinates.

Parameters

xi
eta

child() [1/2]

virtual Triangle3d * concepts::Triangle3d::child ( uint  i )

virtual

Returns a child. If no children exist, four new children are created. The triangle is cut into four new triangles by joining the midpoints of its edges.

Parameters

i	Index of the child to be returned.

Implements concepts::Cell2.

child() [2/2]

virtual const Triangle3d * concepts::Triangle3d::child ( uint  i ) const

virtual

Returns a child. If no children exist, none are created and 0 is returned.

Parameters

i	Index of the child to be returned.

Implements concepts::Cell2.

clone()

Triangle3d * concepts::Triangle3d::clone ( Triangle &  cntr, MapTriangle3d *  map  ) const

inline

Returns a copy of itself.

Definition at line 801 of file cell2D.hh.

connector()

Triangle & concepts::Triangle3d::connector ( ) const

inlinevirtual

Returns the triangle connector (topology)

Implements concepts::Cell2.

Definition at line 778 of file cell2D.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]

Real3d concepts::Triangle3d::elemMap ( const Real2d &  coord_local ) const

inlinevirtual

Element map from point local coordinates in 2D.

Implements concepts::Cell2.

Definition at line 789 of file cell2D.hh.

elemMap() [3/3]

virtual Real3d concepts::Cell2::elemMap ( const Real3d &  coord_local ) const

inlinevirtualinherited

Element map from point local coordinates in 3D

Reference element is 2D, third component is omitted.

Reimplemented from concepts::Cell.

Definition at line 104 of file cell.hh.

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::Triangle3d::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Implements concepts::Cell.

map()

const MapTriangle3d * concepts::Triangle3d::map ( ) const

inline

Returns the element map.

Definition at line 798 of file cell2D.hh.

vertex()

Real3d concepts::Triangle3d::vertex ( uint  i ) const

virtual

Returns the coordinates of the ith vertex.

Implements concepts::Cell2.
