Detailed Description

A class to define a 2-noded linear 1D Segment

This class defines a 2-noded linear 1D interface surface segment.

Important:
Upon construction, the user must assure that the nodes attached to this segment are given in counter-clockwise order:

      <--|       o Node 1
  domain |       | 
       --        | --> outward normal n to Seg 2
                 | 
                 | Seg 2
       Seg 1     |
    o------------o Node 0
   Node 0 |  Node 1
          | 
          | outward normal n to Seg 1
          | 
          v

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_Linear1D class supports the ostream& operator <<

MOERTEL::Segment_Linear1D::Segment_Linear1D (  int  id, int  nnode, int *  nodeId, int  out )  [explicit]

Standard Constructor. Parameters: 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 along the interface outlevel  : Level of output to stdout to be generated by this class (0-10)

MOERTEL::Segment_Linear1D::Segment_Linear1D (  int  out  )  [explicit]

Empty Constructor. To be used for communicating Segment_Linear1D classes among processes together with Pack and UnPack

MOERTEL::Segment_Linear1D::Segment_Linear1D (  MOERTEL::Segment_Linear1D &  old  )

Copy Constructor. Makes a deep copy of a Segment_Linear1D

Member Function Documentation

double MOERTEL::Segment_Linear1D::Metric (  double *  xi, double  g[], double  G[][3] )  [virtual]

Build the covariant basis vectors and metric tensor at a given local coord in this segment. In this case of a 1D segment, there is 1 cov. basis vector and the metric tensor is a scalar representing its length. Implements MOERTEL::Segment.
