void Nektar::NekMeshUtils::Prism::OrientPrism ( )

protected

Orient prism to align degenerate vertices.

Orientation of prismatric elements is required so that the singular vertices of triangular faces (which occur as a part of the collapsed co-ordinate system) align. The algorithm is based on that used in T. Warburton's thesis and in the original Nektar source.

First the points are re-ordered so that the highest global IDs represent the two singular points of the prism. Then, if necessary, the nodes are rotated either clockwise or counter-clockwise (w.r.t to the p-r plane) to correctly align the prism. The #orientation variable is set to:

0 if the prism is not rotated;
1 if the prism is rotated clockwise;
2 if the prism is rotated counter-clockwise.

This is necessary for some input modules (e.g. #InputNek) which add high-order information or bounary conditions to faces.
