B modeling
==============

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

Curved elements are modeled by POU_D_T elements (20 elements per bend).

The straight elements are modeled by POU_D_TG elements.

Characteristics of the mesh

.. csv-table::

    "Number of knots:", "51", "Number of meshes and types:", "10 POU_D_TG
    40 POU_D_T"



notes
---------

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


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

Structure frequencies (full mass matrix).
