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


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

Loading and boundary conditions are modelled by:


.. code-block:: text

    DDL_IMPO: (GROUP_NO: NOEHGFE, DY: 0.)

    LIAISON_DDL :( NOEUD :( N1 NXXX), DDL :( 'DY', 'DY'), COEF_MULT :( 1, -1), COEF_IMPO :0.)

for all nodes belonging to edge :math:`\mathrm{AD}` (:math:`{u}_{z}` uniform on :math:`\mathrm{ad}`)


.. code-block:: text

    PRES_REP: (GROUP_MA: AH, PRES: p (t))

where :math:`p(t)` is the positive function defined :ref:`précédemment <V6.01.001-conditions-aux-limites-et-chargements>`.


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


.. csv-table::

    "Number of nodes:", "381"
    "Number of meshes and types:", "94 elements QUAD8"



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

The parameters of the result data structure are tested:


.. csv-table::

    "**Identification**", "**Reference**", "**Test**", "**Tolerance**"
    "INSTpour NUME_ORDRE =7", "60.0"," 60.0", "ANALYTIQUE ", "0, 10%"
    "ITER_GLOB for NUME_ORDRE =7", "3"," NON_REGRESSION "," 0.00%"



.. csv-table::

    "**Identification**", "**Reference**", "**Test**", "**Tolerance**"
    ":math:`{\varepsilon }_{{v}_{\mathrm{rr}}}` at point :math:`E` to :math:`t=60s` ", "0.0000E+000"," NON_DEFINI "," 0.5%"
    ":math:`{\varepsilon }_{{v}_{\mathrm{zz}}}` at point :math:`E` to :math:`t=60s` ", "0.0000E+000"," NON_DEFINI "," 0.5%"



notes
---------

We stopped at :math:`t=60s` so as not to have too long a calculation time.
