      OBJET1  =  INTG  ('ELEM') MODL1 CHAM1 (MOT1) (CAR1) ;


    Description :
    _____________

    The INTG operator performs the integration of a field component
 either on the region where it has been defined, in which case the
 result is a number, or on each element ('ELEM' option), in which
 case the result is a field by elements.

      Contents :
      __________


      MODL1  : model object (MMODEL type)

      MOT1   : name of the component (MOT type)
               useless if the field has a single component

      CHAM1  : field containing the component to be integrated
               (MCHAML type)

      CAR1   : field of geometrical properties (MCHAML type,
               CARACTERISTIQUES subtype)

      OBJET1 : generated object

               - number (FLOTTANT type) if the integration is
                 performed in the region where the component has
                 been defined

               - field by elements (MCHAML type, SCALAIRE subtype)
                 if the integration is performed on each element
                 (option with the key word 'ELEM'). Its values are
                 defined at the center of gravity of the elements.


    CAUTION :   For the shells, the integration region corresponds to
    ---------   the shell surface, and, for the beams, the integration
                region is the beam mid-line.
                If an integration is requested on the volume of these
                elements, the field of geometrical properties
                CAR1 will have to be supplied.
                (MCHAML type, CARACTERISTIQUES subtype)
