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.
