Detailed Description

The ID of a facet (edge in 2D and face in 3D) encodes an element ID and the local facet's ID internal to the element.

For internal facets, element ID starts with 1, and internal ID starts with 0 and must be smaller than 15. For border facets, the element ID correspondes to the numbering of border facets between 1 and the number of border facets, and the local edge ID is BndID=15.
