E modeling
==============


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

The beam is meshed in massive quadratic elements HEXA20.

The beam is embedded at the level of section :math:`\mathrm{surf1}`. It is subjected to a unit shear force which is modelled by a linear load density :math:`\mathrm{fz}` applying to the 4 SEG3 cells constituting the upper edge :math:`\mathrm{L2}`.


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

The beam is meshed with 640 massive quadratic HEXA20 elements.

The model has 3665 knots.


Tested sizes and results
------------------------------

We test the value of the arrow according to :math:`z` of the middle node of the section where we are applying the load (node :math:`\mathrm{N62}`).

.. csv-table::

    "**Identification**", "**Reference**", "**Aster**", "**% difference**"
    ":math:`\mathit{Dz}` from node :math:`\mathrm{N62}` ", "-8.0E-7", "-7.9523E-7", "-0.596"
