Reference problem
=====================

Geometry
---------

We consider a beam of length :math:`1m` oriented according to :math:`X` or according to :math:`Z` depending on the models.

Loads
------------

Boundary conditions
~~~~~~~~~~~~~~~~~~~~~~~~

In each case, node :math:`A` is embedded. Then, depending on the type of moment tested, node :math:`B` can either be left free or supported in a given direction.


Divided moments
~~~~~~~~~~~~~~~~~

The keywords MX, MY, MZ, MZ, MT, MFY and MFZ are applied in turn. The load is linear on the beam:

.. csv-table::

    "Knot", ":math:`A` "," :math:`B`"
    "Value (N.m/m)", "1000", "2000"


These non-constant loads are affected by the AFFE_CHAR_MECA_F command.

To test distributed moments affected by the AFFE_CHAR_MECA command, we complete this list with constant loads.
