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


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

We use a 2D_ FLUIDE, D_ PLAN, 2D_, 2D_ FLUI_STRU, 2D_, D_ PLAN_ABSO and 2D_ FLUI_ABSO modeling in coupled linear dynamics (:math:`(u,p)` formulation). IFS


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

The characteristics of the mesh are identical to modeling A (see paragraph :ref:`3.2 <RefNumPara__1584_607860470>`).


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** 4.3-1 **: Quantities tested for B modeling**

.. 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 A. In general, the values obtained are very similar with a maximum error of less than **1.e -08%**.
