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

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

The model is composed of 450 Timoshenko straight beam elements.


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

It consists of 450 POU_D_T elements.


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

.. csv-table::

    "**Type of effort**", "**Reference**", "**Accuracy (%)**"
    ":math:`{V}_{y}(0°)` ", "0.0000", "0.4 (absolute)"
    ":math:`{V}_{y}(6°)` ", "0.0000", "0.01 (absolute)"
    ":math:`N(60°)` ", "—1.000E+02", "0.100 (relative)"
    ":math:`\mathit{MFZ}(42°)` ", "0.0000", "0.01 (absolute)"



Variation in mesh refinement
------------------------------------

Initially, the mesh for this test consisted of 30 meshes modelled in POU_C_T. With this refinement the results with the POU_D_T elements are very good except for :math:`{V}_{y}(0°)`:


.. csv-table::

    "**Type of effort**", "**Reference**", "**Deviation (%)**"
    ":math:`{V}_{y}(0°)` ", "0.0000", "5.23 (absolute)"
    ":math:`{V}_{y}(6°)` ", "0.0000", "1E-11 (absolute)"
    ":math:`N(60°)` ", "—1.000E+02", "1,3E-3 (relative)"
    ":math:`\mathit{MFZ}(42°)` ", "0.0000", "1E-12 (absolute)"


With 450 stitches, we only get a difference of 0.34 on :math:`{V}_{y}(0°)`.
