Modeling A
==============


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,\mathrm{\varphi })` formulation). IFS

This modeling is created to calculate a comparison base for formulation :math:`(u,p)`.

**Figure** 3.2-a **: 2D dam mesh**

In the we show the dam mesh which will be composed of 908 linear quadrangular surface elements, 324 linear triangular surface elements and 1151 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** 3.3-1 **: Quantities tested for modeling A**

.. csv-table::

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


We cannot say anything in absolute terms about the precision of these values because we are testing non-regression values.
