v3.01.108 SSLL108 - 2D discrete elements

Summary:

The problem is almost static linear in structural mechanics.

The response of a bar, modelled by 10 discrete elements, to a loading under tension is analyzed in order to validate the two-dimensional discrete elements.

A single modeling uses both the operators MECA_STATIQUE, and STAT_NON_LINE, to validate the use of these elements (whose behavior remains linear) with other finite elements with any behavior.
