  Operateur CNEQ                            Voir aussi :
   --------------   
      CHPO2 =  CNEQ  MODL1  | CHPO1 | ( CAR1 )  ;
                            | CHAM1 |


    Description :
    ____________

    The CNEQ operator calculates the field of nodal values 
 which are equivalent to a volumetric field. For instance, it makes
 it possible to calculate nodal forces corresponding to the weight
 or to centrifugal forces.


      Contents :
      __________


      MODL1 : model object (MMODEL type)

      CHPO1 : volumetric field defined at the nodes (CHPOINT type)

      CHAM1 : volumetric field defined in the elements (MCHAML type)

      CAR1  : field of geometrical properties (MCHAML type,
              CARACTERISTIQUES subtype) required for some elements
              (beams, shells, etc..)

      CHPO2 : field of nodal values (CHPOINT type)


      Note  :  For the time being, this operator only works for 
      ________   MECANIQUE models and for the solid elements
                 DKT and COQ4. The volumetric fields must have
                 components identified by force names.
               It allows now to define the source term due to
               the external vector potential in the MAGNETODYNAMIQUE
               formulation. The volumetric fields must have
                 components AX AY AZ.
