Items. VCN and. VEN
-------------------


.. code-block:: text

    '. VCN ': S V R long=nbmode*nbconnors

    '. VEN ': S V R long=nbmode

nbconnorscorresponds to the number of discretization points for the value of the Connors constant accumulated for all zones.

The objects. VCNet. VENn only exist if:

FAISCEAU_TRANS + coupling = OUI + BASE_MODALE/AMOR_REDUI_CONN


.. csv-table::

    "V (imode, iconnors)", "value of the critical speed calculated for the imodesemode and for the iconorsum value of the Connors constant."
    "V (imode)", "value of the effective speed of imodesemode"





sd_table data structure
----------------------------

An sd_table type concept containing a single NOM_CHAM parameter. It contains the names of all the sd_cham_nodes modal movements disturbed by the flow.




sd_l_table data structure
------------------------------

This data structure only exists in the case of a FAISCEAU_AXIAL configuration.

This sd_l_table contains a single sd_table under the name MATR_GENE.

This sd_table has the following parameters:


* NUME_VITE list of integers describing the list of fluid speed numbers,


* VITE_FLUI describing the value of the fluid speed,


* MATR_MASS for the various generalized mass matrices (one per fluid speed),


* MATR_AMOR for the various generalized damping matrices (one per fluid speed)


* MATR_RIGI for the various generalized stiffness matrices (one per fluid speed)

We also store a NUME_DDL_GENEcommun for all these matrices. This NUME_DDL_GENEa shape (K8). NUXXXoù the XXXest determined by GNOMSD. The name of the concept is therefore based on the user name of the concept sd_melasflumbut is also stored in the concept of generalized matrices.

The same remark also applies to the fields stored in the table. They have a PROF_CHNO in common.
