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


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

We use a 3D_ FLUIDE, 3D, FLUI_STRU,,, 3D_,, 3D_ ABSO and 3D_ FLUI_ABSO modeling in coupled linear dynamics (formulation :math:`(u,p)`). IFS

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

The mesh is generated by extruding the 2D mesh of the A and B models of a single element into the depth. This mesh contains 908 linear hexahedra, 324 linear prisms, and 2302 nodes.


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

We test the accelerations at time :math:`t=0.98s` at the post-processing points for the X and Y directions:

**Table** 5.3-1 **: Quantities tested for modelling** C

.. csv-table::

    "**Identification**", "**Reference type**"
    "A-AX node", "AUTRE_ASTER"
    "A-AY knot", "AUTRE_ASTER"
    "B-AX node", "AUTRE_ASTER"
    "B-AY knot", "AUTRE_ASTER"
    "C-AX node", "AUTRE_ASTER"
    "C-AY knot", "AUTRE_ASTER"
    "D-AX node", "AUTRE_ASTER"
    "D-AY node", "AUTRE_ASTER"


These values are compared directly with the solution obtained in modeling B. In general, the values obtained are practically identical with a maximum error of less than **1e-08%**.
