.. image:: images/modelisation_A.png



.. csv-table::

    "Découpage :", "28 éléments en longueur,"
    "", "8 éléments en largeur."


Conditions aux limites - chargement (trois calculs pour trois choix):


*   calcul a: chargements scalaires et dualisation de la condition de Dirichlet:


.. code-block:: text

    TEMP_IMPO ( NOEUD= 'N1',    TEMP_SUP= 0., TEMP_MIL= 0., TEMP_INF= 0.)
    ECHANGE ( GROUP_MA ='GRSD1', COEF_H_SUP : 10., COEF_H_INF = 10.,
    TEMP_EXT_SUP = -50., TEMP_EXT_INF = -50.)
    ( GROUP_MA ='GRSD2', COEF_H_SUP = 10., COEF_H_INF = 10.,
    TEMP_EXT_SUP = 50., TEMP_EXT_INF = 50.)


*   calcul b: chargements fonctions constantes et dualisation de la condition de Dirichlet :

    comme ci-dessus, mais avec des fonctions constantes ayant mêmes valeurs.


*   calcul c: chargements scalaires et chargement "cinématique":


.. code-block:: text

    THER_IMPO (NOEUD= 'N1', TEMP_SUP= 0., TEMP_MIL= 0., TEMP_INF= 0.)
