    Operateur PSCAL                          Voir aussi : PMIX
    ---------------                                       PVEC   

    Description :
    _____________

    The functions of this operator vary with the arguments :

    ------------------
    |  1st function  |
    ------------------

    FLOT1 = VEC1  PSCA VEC2  ;

    Description :
    _____________

    The PSCA operator performs the scalar product of two vectors.

    Contents :
    __________

    VEC1, VEC2 : vectors (POINT or TABLE type, VECTEUR subtype)

    FLOT1      : result of the scalar product  (FLOTTANT type)

    ------------------
    |  2nd function  |
    ------------------

    OBJ3 = PSCA OBJ1 OBJ2 LMOTS1 LMOTS2  ;

    Description :
    _____________

    The PSCA operator performs the scalar product of two fields
 by points or by elements. The result is obtained by adding, at each 
 support point the products of the components defined for each field.


    Contents :
    __________

    OBJ1  : field by points (CHPOINT or MCHAML type)

    OBJ2  : field by points (CHPOINT or MCHAML type)

    LMOTS1 : list of the components (LISTMOTS type) of the CHPO1
             field

    LMOTS2 : list of the components (LISTMOTS type) of the CHPO2
             field

    OBJ33  : generated object (CHPOINT or MCHAML  type)

    Example :
    _________

   If the components first field  are UX,UY,UZ and those of second
 are FX,FY,FZ, the following calculation (UX*FX)+(UY*FY)+(UZ*FZ)
 will be performed at each support node .
 
    NOTE : for fields by elements  sub-meshes ,support nodes ,harmonics 
    are mandatorily the same  for entry fields  ( operate requested
    conversions before  ( CHANGER , REDUIRE ....)
