    Description :
    ____________

    The FORCE operator constructs a force field which results from
 a localized force.

    Contents :
    __________

    The force can be defined :

    - either by a vector
    - or by component values


     VEC1  : vector (POINT type) whose components are the force
             values with respect to the coordinate axis.

     MOTi  : component names (MOT type)

     VALi  : component values (FLOTTANT type) of MOTi name

     GEO1  : locus onto which the force is applied
             (POINT or MAILLAGE type)

    Note :
    _______

    VEC1 must be specified before GEO1.

    The possible names for the forces are :

      for a computation in mode PLAN CONT :  FX   FY
      for a computation in mode PLAN DEFO :  FX   FY
      for a computation in mode PLAN GENE :  FX   FY  FZ(*)
      for a computation in mode AXIS      :  FR   FZ
      for a computation in mode FOUR      :  FR   FZ  FT
      for a computation in mode TRID      :  FX   FY  FZ

    (*)  only at the node supporting the additionnal unknowns

    VEC1 force is spread over the different points of GEO1.

    Example :
    _______

    If GEO1 contains 50 points, the force applied to each point
 is the 1/50 of VEC1 (or 1/50 of VALi).
