Example of use
=====================

Construction of a thermal transient from a function:

The main commands used to build an evol_ther concept result have been defined below.

Definition of a list of moments.

.. code-block:: text
 lr8 = DEFI_LIST_REEL (DEBUT = 0.E0,
INTERVALLE =( _F (JUSQU_A =5.e-3, NOMBRE =10),
_F (JUSQU_A =5.e-2, NOMBRE = 9),
_F (JUSQU_A =4.e-0, NOMBRE =79),
_F (JUSQU_A =6.e-0, NOMBRE =20),)
)

Definition of a function of the parameter 'INST'.

.. code-block:: text
 fct1 = DEFI_FONCTION (NOM_PARA = 'INST'
VALE = (0.0, 20.0,
0.5, 25.0,
2.0, 54.0,
10.0, 13.40,)
PROL_DROIT = 'LINEAIRE',
PROL_GAUCHE = 'LINEAIRE',
)

Construction of a field at the function nodes, the same function fct1 is assigned to all the nodes of the mesh.

.. code-block:: text
 ch = CREA_CHAMP (TYPE_CHAM =' NOEU_TEMP_F ', OPERATION =' AFFE ',

    MAILLAGE =ma, AFFE =_F (TOUT =' OUI ', NOM_CMP =' TEMP', VALE_F =fct1,),
)

    ...

Creation of the concept result TEMPE, built from the field at the function nodes ch. We limit ourselves to the order number 20 corresponding to the value 0.1. The data structure will have 20 order numbers from 1 to 20.


.. code-block:: text
 TEMPE = CREA_RESU (OPERATION = 'AFFE',
                   TYPE_RESU = 'EVOL_THER',
                   AFFE = (_F (CHAM_NO = ch,
                               NOM_CHAM = 'TEMP',
                               LIST_INST = lr8,
                               NUME_FIN = 20,),
                         )
                 )
...
