Operands
=========


Operands MODELE/CARA_ELEM/CHAM_MATER
-----------------------------------------


.. code-block:: text

    ♦ MODELE = me,

The name of the model on which the option is calculated.


.. code-block:: text

    ◊ CARA_ELEM = character,

Elementary characteristics associated with the mo model, if it contains structural elements or if the isoparametric elements are assigned a local anisotropy coordinate system.

Only for option ROCH_ELNO:

.. code-block:: text

    ♦ CHAM_MATER = chmat,

Material field. Must contain elastic data and POST_ROCHE material.


Selection of the meshes concerned by the calculation
----------------------------------------------

The keywords TOUT = 'OUI' and GROUP_MA allow the user to choose the meshes on which he wants to do his basic post-processing calculations.


.. code-block:: text

    /TOUT = 'OUI'

All meshes (carrying finite elements) will be treated. This is the by default value.


.. code-block:: text

    /GROUP_MA = l_grma

Only the meshes included in l_grma will be processed.


Operand INST
-------------


.. code-block:: text

    ◊ INST

Value of the moment allowing the evaluation of possible functions in the material parameters for the calculation of the heat flow.


Thermal options
------------------

Elementary thermal calculation options can be calculated from a temperature field:


.. code-block:: text

    ♦ TEMP = time

For these calculations we need the material field associated with the mo model:


.. code-block:: text

    ♦ CHAM_MATER = to kill,

The options available are:


.. code-block:: text
 | 'ELGA_FLOW',
| 'FLUX_ELNO',

Their meaning is given in [:external:ref:`U4.81.04 <U4.81.04>`].

In the case of models AXIS_FOURIER and PLAN_FOURIER, you can specify the harmonic number by the keyword: MODE_FOURIER.


Acoustic options
-------------------

Elementary calculation options in acoustics can be calculated from a complex pressure field:


.. code-block:: text

    ♦ PRES = near

The available option is:


.. code-block:: text
 | 'PRAC_ELNO'

Calculation of the real and imaginary parts of the pressure field by element at the nodes.


Option COOR_ELGA
----------------

Calculate the coordinates and weights of the Gauss points for each element.


Option ROCH_ELNO
----------------

This option places the values of certain material parameters and certain beam characteristics in the form of a field at the nodes per element. The output field has 10 components described in the following table:


.. csv-table::

    "**Components**", "**Correspondence**"
    "E", "Young's module"
    "K_ FACT ", "Parameter FACTEURde POST_ROCHE"
    "N_ EXPO ", "Parameter EXPOSANTde POST_ROCHE"
    "A", "Beam cross section area (circular)"
    "I", "Inertia of the beam section (circular)"
    "R", "Outer radius of the beam section (circular)"
    "EP", "Pipe Thickness"
    "I2", "Inertia value at the other nodes of the same mesh"
    "R2", "Value of the radius at the other nodes of the same mesh"
    "EP2 ", "Thickness value at the other nodes of the same mesh"


This option is used for the specific needs of macro command POST_ROCHE.

Attention, the parameter E must not be a function.
