    ♦ MATR_RIGI = K1,

Name of the assembled stiffness matrix (with linear relationships to eliminate)

If the keyword MATR_ASSE is not used, it is the matrix K1 that is "reduced" to create the result matrix (M2).


Operand MATR_ASSE
------------------


.. code-block:: text

    ◊ MATR_ASSE = M1,

Name of the assembled matrix mass, damping,... (no stiffness) that you want to reduce.

If this keyword is used, it is the matrix M 1 that is "reduced" to create the result matrix (M2).


Operand TITRE
--------------


.. code-block:: text

    ◊ TITRE = title,
