Operands
=========




Operand RESULTAT_REDUIT
------------------------


.. code-block:: text

    ♦ RESULTAT_REDUIT = base2, [result_saster]

This keyword gives the result data structure (evol_ther or evol_noli) that comes from the reduced calculation with THER_NON_LINE or STAT_NON_LINE. This data structure contains all the information needed to reconstruct the results on the model given by the MODELE keyword.




Operand MODELE
---------------


.. code-block:: text
 ♦ MODELE = model [modele_sdaster]


    Name of the model on which the result data structure will be rebuilt. It should be different from the model on which the result RESULTAT_REDUIT data structure is based.




Tag factor CHAM_GD
------------------------

.. code-block:: text

♦ CHAM_GD = _F (

         ♦ NOM_CHAM = /' DEPL ', [TXM]

.. code-block:: text
 /' TEMP ',
/' SIEF_NOEU ',
/' FLUX_NOEU ',
/' SIEF_ELGA ',
/' VARI_ELGA ',
♦ BASE = base, [emp_mode]
♦ OPERATION = /' GAPPY_POD ', [TXM]
/' COMB ',
◊ GROUP_NO_INTERF = grno, [grno])


    This repeatable factor keyword allows you to define which fields should be rebuilt and in what way.

    NOM_CHAM gives the type of field to be rebuilt. The current list is exhaustive (you cannot rebuild a field that does not belong to this list) The command prohibits reconstructing a field that does not exist in the initial data structure given by RESULTAT_REDUIT.

    Each reconstructed field needs its empirical base given by the keyword BASE (calculated by DEFI_BASE_REDUITE). Consistency checks are made between the database given by the user and the reconstructed field.

    A field can be reconstructed in two ways using the OPERATION keyword:

    - By "modal" recombination: it is simply the weighted sum of the empirical modes by the reduced coordinates (see TABL_COOR_REDUIT).

    - By Gappy- POD. The operation consists in reconstructing the reduced coordinates by minimizing the difference between the field partially calculated on the reduced domain (see commands THER_NON_LINE and STAT_NON_LINE) and in then recalculating the complete field on the domain by linear combination.

The GROUP_NO_INTERF keyword gives the group of nodes defining the interface, the reduced domain, and the rest of the model (see commands THER_NON_LINE and STAT_NON_LINE).

Operand TABL_COOR_REDUIT
-------------------------

.. code-block:: text


    ◊ TABL_COOR_REDUIT = tabl_coor,


    When recalculating a field by modal combination, it is necessary to have the reduced coordinates of the calculation. These coordinates are stored in a data structure table with the name 'COOR_REDUIT' that is attached to the result data structure. It can be retrieved using the RECU_TABLE operator. For example:


    cocoredp= RECU_TABLE (co=Resunl, NOM_TABLE =' COOR_REDUIT ')


    But if you get back the empirical base previously calculated by an operator like LIRE_RESU (especially in the MED format), this table is not available. The TABL_COOR_REDUIT operator therefore allows it to be given to REST_REDUIT_COMPLET.


    It is therefore necessary beforehand to have saved this table at the same time as the non-linear result (with a IMPR_TABLE), then to retrieve it (with a LIRE_TABLE) to give it to REST_REDUIT_COMPLET.




Output data structure
------------------------------


.. code-block:: text

    The output data structure is a code_aster sd_result standard.
