C modeling
==============

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

Curved elements are modeled by POU_D_T elements (10 elements per bend).

Straight elements are modeled by POU_D_E elements (10 elements per right beam).

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

.. csv-table::

    "Number of knots:", "51", "Number of meshes and types:", "30 POU_D_E
    20 POU_C_T"



notes
---------

The modes are standardized as follows: largest component (degree of freedom of translation or rotation) to :math:`1`.


Tested sizes and results
