Detailed Description

Class to describe an element of the boundary. A boundary has a type (Neumann, Dirichlet) and a function associated.

Boundary conditions of type Robin are not yet implemented.

It is possible to use this class in the following way:

Boundary(Boundary::NEUMANN, ParsedFormula("(x)"));

since the ParsedFormula is cloned (ie. it is copied) before the temporary object is destroyed.

Constructor & Destructor Documentation

Boundary() [1/4]

concepts::Boundary::Boundary

(

)

Default constructor. Initializes the type to FREE.

Boundary() [2/4]

concepts::Boundary::Boundary

(

const enum boundaryTypes

type

)

Constructor. The type of the boundary condition must be one of FREE, DIRICHLET, NEUMANN or CONNECT. In this constructor, no formula can be given. It is always evaluated to 0 by default.

Boundary() [3/4]

concepts::Boundary::Boundary	(	const enum boundaryTypes	type,
		const Formula< Real > &	frm
	)

Constructor. The type of the boundary condition must be one of FREE, DIRICHLET or NEUMANN.

Parameters

type	Boundary type
frm	Formula (can be a temporary object since it is copied)

Boundary() [4/4]

concepts::Boundary::Boundary	(	const enum boundaryTypes	type,
		const char *	frm
	)

Constructor. The type of the boundary condition must be one of FREE, DIRICHLET or NEUMANN. The formula can be given as a string which will be used to create a ParsedFormula.

Parameters

type	Boundary type
frm	Formula as a string

Member Function Documentation

info()

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

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::OutputOperator.

isNull()

bool concepts::Boundary::isNull ( )

inline

Definition at line 82 of file boundary.hh.

operator()() [1/3]

Real concepts::Boundary::operator()	(	const Real	x,
		const Real	t = 0.0
	)		const

Application operator. Calculates the value of the boundary function at a specific point.

operator()() [2/3]

Real concepts::Boundary::operator()	(	const Real2d &	x,
		const Real	t = 0.0
	)		const

Application operator. Calculates the value of the boundary function at a specific point.

operator()() [3/3]

Real concepts::Boundary::operator()	(	const Real3d &	x,
		const Real	t = 0.0
	)		const

Application operator. Calculates the value of the boundary function at a specific point.

type()

enum boundaryTypes concepts::Boundary::type ( ) const

inline

Returns the type of the boundary condition.
