Modeling A
==============

Characteristics of modeling
-----------------------------------

A DIS_TR_L element with 2 nodes of zero size (idem [:ref:`§1.1 <§1.1>`]).

An N2 node: we block everything.

An N3 node: we impose :math:`\mathrm{Fy}` in :math:`\mathrm{500 }N` steps with the time map:


.. csv-table::

    ":math:`t` ", "0. ", "4. ", "6. ", "10. ", "12."
    ":math:`F(t)` ", "0. ", "4. ", "2. ", "6. ", "4."



Characteristics of the mesh
----------------------------

1 SEG2.

2 knots.


Tested sizes and results

**General:**

*Behavior* ARME *can also be used in Nonlinear Dynamic Analysis but is not tested.*
