Constructor & Destructor Documentation

MOERTEL::Projector::Projector	(	bool	twoD,
		int	outlevel
	)			[explicit]

Constructor.

Constructs an instance of this class.
Note that this is not a collective call as projections are performed in parallel by individual processes.

Parameters:

	twoD	: True if problem is 2D, false if problem is 3D
	outlevel	: Level of output information written to stdout ( 0 - 10 )

Member Function Documentation

bool MOERTEL::Projector::ProjectNodetoSegment_NodalNormal	(	const MOERTEL::Node &	node,
		MOERTEL::Segment &	seg,
		double	xi[]
	)

Project a Node onto a Segment along the Node 's normal.

Used to project a Node from the slave side onto a Segment on the mortar side

This method will compute the coordinates of a projection of a Node in the local coordinate system of a Segment. The projection point will not neccesarily fall inside the Segment. However, if the projection point is far outside the segment's boundaries, problems with the internal nonlinear iteration might occur and a warning is issued when convergence can not be achieved in a limited number of iterations.

Parameters:

	node	(in): Node to project
	seg	(in) : Segment to project on
	xi	(out) : Local coordinates if projection of Node in Segment 's coordinate System

bool MOERTEL::Projector::ProjectNodetoSegment_Orthogonal_to_Slave	(	const MOERTEL::Node &	snode,
		MOERTEL::Segment &	seg,
		double	xi[],
		MOERTEL::Segment &	sseg
	)

Project a Node onto a Segment orthogonal another Segment (2D problems only).

Used to project a Node from the slave side onto a Segment on the mortar side orthogonal to some slave Segment

This method will compute the coordinates of a projection of a Node in the local coordinate system of a Segment. The projection point will not neccesarily fall inside the Segment. However, if the projection point is far outside the segment's boundaries, problems with the internal nonlinear iteration might occur and a warning is issued when convergence can not be achieved in a limited number of iterations.

Parameters:

	node	(in): Node to project
	seg	(in) : Segment to project on
	xi	(out) : Local coordinates if projection of Node in Segment 's coordinate System
	sseg	(in) : Segment to project orthogonal to

bool MOERTEL::Projector::ProjectNodetoSegment_SegmentNormal	(	const MOERTEL::Node &	node,
		MOERTEL::Segment &	seg,
		double	xi[]
	)

Project a Node onto a Segment along the interpolated outward normal field of the Segment.

Used to project a Node from the mortar side onto a Segment on the slave side

This method will compute the coordinates of a projection of a Node in the local coordinate system of a Segment. The projection point will not neccesarily fall inside the Segment. However, if the projection point is far outside the segment's boundaries, problems with the internal nonlinear iteration might occur and a warning is issued when convergence can not be achieved in a limited number of iterations.

Parameters:

	node	(in): Node to project
	seg	(in) : Segment to project on
	xi	(out) : Local coordinates if projection of Node in Segment 's coordinate System

bool MOERTEL::Projector::ProjectNodetoSegment_SegmentOrthogonal	(	const MOERTEL::Node &	node,
		MOERTEL::Segment &	seg,
		double	xi[]
	)

Project a Node onto a Segment orthogonal to the Segment (2D problems only).

Used to project a Node from the mortar side onto a Segment on the slave side

This method will compute the coordinates of a projection of a Node in the local coordinate system of a Segment. The projection point will not neccesarily fall inside the Segment.

	xi	(out) : Local coordinates if projection of Node in Segment 's coordinate System
