Constructor & Destructor Documentation

TrianglesP2::TrianglesP2	(	concepts::Mesh2 &	msh,
		uint	level,
		concepts::BoundaryConditions *	bc = `0`
	)

Constructor.

Parameters:

msh	Mesh
level	Number levels for initial refinement
bc	Boundary conditions

virtual TrianglesP2::~TrianglesP2 ( ) [virtual]

Member Function Documentation

void TrianglesP2::deactivate_ ( concepts::Connector1 & edg ) [private]

Deactives children of this edge and the new vertex.

virtual uint TrianglesP2::dim ( ) const [inline, virtual]

Returns the dimension of the space.

Implements concepts::Space< Real >.

Definition at line 112 of file triangleP2.hh.

virtual std::ostream& TrianglesP2::info ( std::ostream & os ) const [protected, virtual]

Returns information in an output stream.

Reimplemented from concepts::Space< Real >.

virtual uint TrianglesP2::nelm ( ) const [inline, virtual]

Returns the number of elements in the space.

Implements concepts::Space< Real >.

Definition at line 113 of file triangleP2.hh.

void TrianglesP2::rebuild ( )

Rebuilds the space.

void TrianglesP2::rebuild0_	(	concepts::Connector2 &	cntr,
		const int	l,
		int &	L
	)		`[private]`

Determines maximal level and sets control information.

rebuild0_ is called recursively.

Parameters:

cntr	Support of the element
l	Current level
L	Maximal level

void TrianglesP2::rebuild1_	(	concepts::Triangle2d &	cell,
		concepts::TColumn< Real > *	T0 = `0`
	)		`[private]`

Builds the elements for triangles.

This routines assigns degress of freedom to vertices, creates T matrices. rebuild1_ is called recursively.

Precondition:: T0 is 0 as there are no S matrices for triangles up to now.

Todo:: S matrices for triangles

Parameters:

cell	Cell of the element
T0	T columns from element on a higher level

virtual TrianglesP2::Scan* TrianglesP2::scan ( ) const [virtual]

Returns a scanner to iterate over the elements of the space.

Implements concepts::Space< Real >.
