The edge reference_element
is K = [0,1]
.
0---------1 x
This one-dimensional reference_element
is then transformed, after the Piola geometrical application, as a segment in a 1D, 2D or 3D physical space, as a geo_element
.
Curved high order transformed geo_element
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.
