Code_Aster implementation
========================

Here we recall the main steps of *Aster* calculation in the case of a calculation using plane deformations, by explicitly specifying where the specifications mentioned above come into play. For the mechanical part, what is specific to the case of a thermo-mechanical calculation has been written in bold.


Thermal study
---------------


* Reading the thermal mesh


.. csv-table::

    "MY= LIRE_MAILLAGE (UNITE =20,)"



* Choice of thermal model


.. code-block:: text

    MOTH2D = AFFE_MODELE (MAILLAGE =MA,

    VERIF =' MAILLE ',

    AFFE =_F (GROUP_MA = ('GMA1', 'GMA2',...),

    PHENOMENE =' THERMIQUE ',

    MODELISATION =' PLAN_DIAG ',),)


* Thermal properties of the material


* Thermal loading


* THER_LINEAIRE or THER_NON_LINE


.. code-block:: text

    THER =...


* Possible post-treatments


Mechanical study
---------------


* Mechanical mesh reading


.. csv-table::

    "MAME = LIRE_MAILLAGE ()", "MAME = CREA_MAILLAGE ()
    MAILLAGE = MY,
    LINE_QUAD =_F (TOUT =' OUI '))"



* Definition of the mechanical model


.. code-block:: text

    MOME = AFFE_MODELE (MAILLAGE = MAME,

    VERIF =' MAILLE ',

    AFFE =_F (GROUP_MA = ('GMA1', 'GMA2',...),

    PHENOMENE =' MECANIQUE ',

    MODELISATION ='D_ PLAN_SI ',),);


* Projection of the thermal calculation if chained calculation on 2 different meshes


.. code-block:: text

    CHTHER = PROJ_CHAMP (METHODE =' COLLOCATION ',
RESULTAT = THER,
MODELE_1 = MOTH2D,
MODELE_2 = MOME,);


* Material characteristics


.. code-block:: text

    CHMAT = AFFE_MATERIAU (MAILLAGE = MAME,
AFFE_VARC = _F (NOM_VARC =' TEMP ',
TEMP_REF = 20. ,
EVOL = CHTER or THER if no projection...)


* Mechanical loads


* STAT_NON_LINE


* Post-treatments
