Example: reading a EUROPLEXUS mesh
------------------------------------------

The universal file IDEAS (logic unit 19) reads the EUROPLEXUS hydrodynamic wire mesh and transforms it into the *Code_Aster* format written on the unit 22. The mesh EUROPLEXUS in *Code_Aster* format is then re-read and placed in the mesh-type concept.


.. code-block:: text

    PRE_IDEAS (UNITE_IDEAS =19, UNITE_MAILLAGE =22)

    Implexus = LIRE_MAILLAGE (UNITE =22,)


Example: creating a result of type 'evol_char'
----------------------------------------------------

The fluid pressure field as a function of time can be read on the universal file IDEAS. This field, defined on the hydrodynamic wire mesh of EUROPLEXUS (in the format of *Code_Aster*), is then projected onto the mechanical mesh of *Code_Aster* for all the moments of definition.


.. code-block:: text

    presplex= LIRE_PLEXUS (UNITE = 19,
FORMAT = 'IDEAS',
MAIL_PLEXUS = plexus,
MAILLAGE = master,
MODELE = modaster,
TOUT_ORDRE = 'OUI',
)


Example: use of the 'evol_char' result
-----------------------------------------------------

The concept 'evol_char' previously defined is used under keyword EVOL_CHAR to manufacture a loading.


.. code-block:: text

    char= AFFE_CHAR_MECA (MODELE = modaster,
...
EVOL_CHAR = presplex,
)

    Other examples of using the LIRE_PLEXUS operator can be found in the command files for test case ZZZZ112, models A, B, C [:external:ref:`V1.01.112 <V1.01.112>`].
