Detailed Description

To describe a node.

A node is characterized by its label, its coordinates, its number of degrees of freedom (DOF) and ``codes" that are associated to each DOF.

Public Member Functions

Constructor & Destructor Documentation

Node

(

)

Default constructor.

Initialize data to zero

Node	(	size_t	label,
		const Point< double > &	x
	)

Constructor with label and coordinates.

Define a node by giving its label and its coordinates x

Member Function Documentation

void DOF	(	size_t	i,
		size_t	dof
	)

Define label of DOF.

Parameters:

[in]	i	DOF index
[in]	dof	Its label

Point<double> getCoord

(

)

const

Return coordinates of node.

Return value is an instance of class Point

double getCoord

(

size_t

i

)

const

Return i-th coordinate of node.

i = 1..3

Referenced by NodeVect::set(), UserData::setBodyForce(), UserData::setDBC(), UserData::setInitialData(), and UserData::setSurfaceForce().

size_t getNbNeigEl

(

)

const

Return number of neighbor elements.

Neighbor elements are those that share node. Note that the returned information is valid only if the Mesh member function getNodeNeighborElements() has been invoked before

bool getOnBoundary

(

)

const

Say if node is a boundary node.

Note this information is available only if boundary sides (and nodes) were determined (See class Mesh).

void setCode

(

int *

code

)

Define codes for all node DOFs.

Parameters:

[in]

code

C-array that contains code for each DOF of current node

void setCode	(	size_t	dof,
		int	code
	)

Define code for a given DOF of node.

Parameters:

[in]	dof	DOF index
[in]	code	Code to assign to DOF

void setCoord	(	size_t	i,
		double	x
	)

Set i-th coordinate.

Parameters:

[in]	i	Coordinate index (1..3)
[in]	x	Coordinate value

void setDOF	(	size_t &	first_dof,
		size_t	nb_dof
	)

Define number of DOF.

Parameters:

[in,out]	first_dof	Label of the first DOF in input that is actualized
[in]	nb_dof	Number of DOF

void setOnBoundary

(

)

Set node as boundary node.

This function is mostly internally used (Especially in class Mesh)
