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



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

For these two models, the degrees of freedom of discretization are, at each node of the support mesh, the three translational displacement components.

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

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