# Calculation of the first 5 rotating modes using the QZ method:

Lmod= CALC_MODE_ROTATION (MATR_RIGI = RIGIDITE,

MATR_MASS = MASSE,

MATR_AMOR = AMOR,

MATR_GYRO = GYASS,

VITE_ROTA =L_ VITROT,

METHODE = 'QZ',

CALC_FREQ =_F (OPTION =' PLUS_PETITE ', NMAX_FREQ =5),

VERI_MODE =_F (STOP_ERREUR =' NON '));

CALC_MODE_ROTATION returns a table (table_container) containing the modal bases calculated for each rotation speed.

The mod_meca_cproduct are named like this: mod_0,… mod_i.. mod_NBV, \(i\) is the index of the rotation speed in VITE_ROTA.
