NekDouble Nektar::SpatialDomains::SegGeom::GetCoord ( const int  i,
const Array< OneD, const NekDouble > &  Lcoord

Given local collapsed coordinate Lcoord return the value of physical coordinate in direction i.

Reimplemented from Nektar::SpatialDomains::Geometry.

StdRegions::Orientation Nektar::SpatialDomains::SegGeom::GetEdgeOrientation ( const SegGeom &  edge1,
const SegGeom &  edge2 
)
static

Get the orientation of edge1.

If edge1 is connected to edge2 in the same direction as the points comprising edge1 then it is forward, otherwise it is backward.

For example, assume edge1 is comprised of points 1 and 2, and edge2 is comprised of points 2 and 3, then edge1 is forward.

If edge1 is comprised of points 2 and 1 and edge2 is comprised of points 3 and 2, then edge1 is backward.

Since both edges are passed, it does not need any information from the EdgeComponent instance.

Backward direction. Vertex 0 is connected to edge 2.
