◆ canonical_faces()

void MeshBase::canonical_faces ( )
protected

Permute nodes of individual elements so that all elements have same edge orientations and aligned sides have same order of their nodes Canonical edge orientation in elements and faces is from nodes of lower local index to higher local index.

Algorithm detals:

  1. Orient all edges from lowe global node id to higher node id, fictional step. (substantial is orientation of yet non-oriented edges of a node in direction out of the node. Can be proven (!?) that this prevents edge cycles of the length 3 (faces with cyclic edges).
  2. Having all faces non-cyclic there exists a permutation of any element to the reference element. Pass through the elements. Sort nodes by global ID.
