     Description :
    ______________

     The purpose of the KENT operator is to calculate the stiffness matrices
     (forces proportionnal to the displacement) necessary for
    studying a structure in a non galilean frame such as a rotating frame.  
      This operator is available for the BARR, POUT, TUYAU, COQUE, MASSIF
      finite elements in 3D and the CERC and MASSIF elements in 2D Fourier.

     RIG1 : Centrifuge stiffness matrix (RIGIDITE type)   
  
                                          
     MODL1: Model object (MMODEL type)

                                    
     MAT1 : Field of material and geometrical properties 
               (MCHAML type, CARACTERISTIQUES subtype)   
  
     VEC1 : Speed of rotation vector (CENTRIFUGE option)
           or variation of speed of variation (EULER option) (POINT type)
     This vector is optional in Fourier modes.
     In such a case, only the Oz component is considered (rotation around this a
     By default, this component is taken equal to 1.

     Option 'CENTRIFUGE': RIG1 is the centrifuge stiffness matrix

     Option 'EULER':  RIG1 is the Euler matrix (the Euler forces exist
                      when the rotation vector is not constant).
