    Description :
    _____________

    The VECT operator constructs a VECTEUR type object from the
 components of :
       - a vector field (case 1),
       - a field by elements of principal stress (case 2),
       - a field by elements of internal variables (cracks) (case 2),
       - a field by elements of other type (case 3).
 
    Contents :
    __________

    
    VEC1   : generated vector (VECTEUR type)

    Case n°1 :

      CHPO1  : vector field (CHPOINT type)

      FLOT1  : coefficient of amplification (FLOTTANT type)
               if positif, the plot will show vectors originating
               from the points.
               if negatif, the vectors will point towards the points
               if omitted, it will be automaticaly computed
      MOT1 | : names of the components of the field associated
      MOT2 |   with the directions Ox, Oy (and possibly
      MOT3 |   Oz in 3D) (MOT type)

      COUL1  : color allocated to the VEC1 vector (MOT type)

    Case n°2 :

      CHAM1   : field by elements (MCHAML type, CONTRAINTES PRINCIPALES 
                or VARIABLES INTERNES subtype)

      CHAM2   : optional field by elements (MCHAML type,
                CARACTERISTIQUES subtype)

      MOD1    : model object (MMODEL type)

      FLOT1   : coefficient of amplification (FLOTTANT type)

      MOCOMP1 : if exists, name of THE component you want to keep
                (MOT type)

      LISMO1  : list of colors allocated to each component
                (LISTMOTS type)
                
    Case n°3 :

      CHAM1   : field by elements (MCHAML type, of subtype different 
                from CONTRAINTES PRINCIPALES and VARIABLES INTERNES)

      MOD1    : model object (MMODEL type)

      FLOT1   : coefficient of amplification (FLOTTANT type)

      MOCOMP1 : name of the components defining the vector
                (MOT type)

      LISMO1  : list of colors allocated to each component
                (LISTMOTS type)


    Notes :
    _________

    The VEC1 vector can be displayed by means of the TRACER
    instruction.

    Il will appear with the FLOT1 amplification and the COUL1 color in
    the first case, and with the FLOT1 amplification and the colors
    given in LISMO1 in the second case.

    In order to get several plots of vectors on the same graph, it is
    possible to apply the ET operator between the VECTEUR type objects.

    The MCHAML of VARIABLES INTERNES is supposed to be a result from
    PASAPAS procedure. Then, the TRACER instruction enables crack
    visualisation.  For 2D analysis (and for shell element) the line
    plotted represent the crack, but for 3D analysis it represent the
    direction perpendicular to the surface of the crack.
