Detailed Description

A class to define a 3-noded triangle 2D Segment.

A class to define a 3-noded triangle 2D Segment

Last update do Doxygen: 20-March-06

This class defines a 3-noded linear 2D triangle interface surface segment.

Upon construction, the user must assure that the nodes attached to this segment are given in counter-clockwise order such that the outward normal to the domain points out from the screen:

                   Node 2
                   / |
                  /  |
                 /   |
                /    |                <-------| 
               /     |         domain surface | 
              /      |                   ------  
             /       |
            /        |
           /         |
        Node 0     Node 1

The reason for this is that the outward normal to the interface is implicitly defined by the orientation of the segments. There is no way for the MOERTEL package to check the orientation of the segments as they are passed in by the user and most obscure results will be produced when the orientation is uncorrect!

The MOERTEL::Segment_BiLinearTri class supports the ostream& operator <<

Constructor & Destructor Documentation

MOERTEL::Segment_BiLinearTri::Segment_BiLinearTri ( int  id,
int  nnode,
int *  nodeId,
int  out 
) [explicit]

Standard Constructor.

Id: A unique positive Segment id. Does not need to be continous among segments
nnode: Number of nodes this segment is attached to
nodeId: Pointer to vector length nnode holding unique positive node ids of nodes this segment is attached to in counterclock-wise orientation looking at the interface such that the outward normal to the domain points out from the screen
outlevel: Level of output to stdout to be generated by this class (0-10)
MOERTEL::Segment_BiLinearTri::Segment_BiLinearTri ( int  out) [explicit]

Empty Constructor.

To be used for communicating Segment_BiLinearTri classes among processes together with Pack and UnPack

MOERTEL::Segment_BiLinearTri::Segment_BiLinearTri ( MOERTEL::Segment_BiLinearTri old)

Copy Constructor.

Makes a deep copy of a Segment_BiLinearTri
