Discretization
==============



Degrees of freedom
------------------

The degrees of freedom are, for each node of the support mesh, the six displacement components (three translations and three rotations).

Stiffness matrix support mesh
------------------------

Finite element support meshes, in displacement formulation, are segments with two nodes SEG2:
