NAME

       edge - reference element (rheolef-7.2)

DESCRIPTION

       The edge reference_element(6) is K = [0,1].

           0---------1
                x

        This one-dimensional reference_element(6) is then transformed, after the Piola
       geometrical application, as a segment in a 1D, 2D or 3D physical space, as a
       geo_element(6).

       Curved high order transformed geo_element(6) Pk edges (k >= 1) are supported for 2D or 3D
       geometries. In these cases, the nodes of an high-order edge are numbered as:

         0----2----1     0--2--3--1    0-2-3-4-1
             P2              P3           P4

        It means that boundary nodes come first, and then are the internal nodes.
