F modeling
==============

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

Ditto modeling D


.. _DdeLink__5594_488461185311:

Modeling with TUYAU_3M elements (SEG4, 3 Fourier modes).


.. _DdeLink__5594_4884611852:

Curved elements are modeled by TUYAU_3M elements (5 elements per elbow).

The straight elements are modeled by TUYAU_3M elements (18 elements in total for the three straight beams: 4 elements for N3N4 and NSN6, 5 elements for the two right parts of N1N2).

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

.. csv-table::

    "Number of knots:", "85", "Number of stitches and types:", "28 TUYAU_3M"



notes
---------

The modes are calculated using method TRI_DIAG: the 9 smallest modes.


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

Structure frequencies (full mass matrix).
