Caractéristiques du maillage
----------------------------


.. csv-table::

    "Nombre de nœuds :", "729"
    "Nombre de mailles et types :", "320 TRIA6"



Remarques
---------

Les conditions limites, :math:`T=100°C` sur :math:`\mathrm{AB}` , et :math:`T=0°C` sur :math:`\mathrm{AD}` , sont incompatibles au point A. *Code_Aster*  applique une "loi de surcharge" qui, dans ce cas, consiste à prendre en compte la dernière condition limite entrée. L'ordre d'affectation des températures imposées a donc une grande influence sur les résultats obtenus.

Dans le cas traité, la température affectée au point :math:`A` est de :math:`0°C` .
