Multiplicity of finite element dofs.

Multiplicities describe groups of dofs whose order changes with the configuration (e.g. the rotation or orientation) of the geometrical entity relative to the actual cell.

In each spatial dimension we accept the following dof multiplicities:

0) Point (1 configuration):

  • single dofs

1) Line (2 possible configurations=orientations):

  • single dofs
  • pairs

2) Triangle (2 orientations and 3 rotations=6 configurations):

  • single dofs
  • pairs
  • triples
  • sextuples

3) Tetrahedron (1 configuration, since it is always the cell):

  • single dofs
