Operands MATR_RIGI/MATR_MASS/MATR_AMOR/MATR_GYRO//INFO//METHODE/OPTION/CHAM_MATER/CARA_ELEM
-----------------------------------------------------------------------------------------

They have the same meaning as in command CALC_MODES [:external:ref:`U4.52.02 <U4.52.02>`].

**Note:**

 *Due to the presence of damping and gyroscopic matrices, only the* QZ *and* SORENSEN *methods are usable*.


Keyword CALC_FREQ
------------------

Plays the same role as in the CALC_MODES [U4.52.02] command, has the same internal keywords with the same values by default.

**Note:**

*The number of modes* :math:`\mathit{nbF}` *is the same for all rotation speeds.*


Operand VITE_ROTA
------------------

List of rotation speeds :math:`\Omega` in :math:`\mathit{rad}\mathrm{/}s`.


OperandKeyword VERI_MODE
--------------------------

The internal operands have the same meaning as in the keyword with the same name in the CALC_MODES [:external:ref:`U4.52.02 <U4.52.02>`] command.
