    Operateur ORIENTER                       Voir aussi : VERS
    ------------------   
    en 2D :   GEO1 = ORIENTER GEO2 ;

    en 3D :   GEO1 = ORIENTER GEO2  | ('DIRECTION') VEC1  | ;
                                    |  'POINT'      POIN1 |


    Description:
    ____________

    The ORIENTER operator constructs a mesh which is identical to
 the initial mesh. However, all its elements liable to be oriented are
 oriented in the trigonometric direction in 2D and in relation to
 their direction with respect to a vector or a point in 3D.

    Contents:
    _________

    GEO2  : initial mesh (MAILLAGE type)

    VEC1  : reference vector for orientation (POINT type) : the scalar
            product beetween VEC1 and the outer normal to each element
            is positive.

    POIN1 : reference point for orientation (POINT type) : the outer
            normal to each element points in the direction of the
            half-space containing POIN1.

    GEO1  : oriented mesh (MAILLAGE type)

    The "orientable" elements have the TRI3/QUA4/TRI6/QUA8/TRI7/QUA9
    type.

    The CUB8 element (for SHB8 shell element) can also be oriented.
 

   Remarks for CUB8 :
   __________________

   It is assumed that there is only one element through the thickness
   and that the 4 first nodes of each element are an out surface 
   of the shell. The cub8 element is oriented in the way that the vector 
   defining the direction goes through the element from the inside 
   surface to the outside surface. The resulting mesh object contains 
   reference to these two surfaces by means of operator FACE (inside 
   surface is number 1 and outside number 2).
