  Operateur DEDOUBLE                       Voir aussi :
    ------------------   
    GEO3 GEO4 = DEDO GE01 GEO2 ;


    Description :
    _____________

    The DEDOUBLE operator duplicates the nodes of the line GEO2 in the
mesh GE01. The result is stored in GEO3 (MAILLAGE type). GEO4 is the
new line corresponding to GEO2.

    Comments:
    _________

    This operator can only be used for two-dimensionnal geometries. GEO2
must be a continuous line (made up with SEG2 or SEG3 elements), without
any bifurcations.

    Example :  
    _________

    OPTI DIME 2 ELEM TRI3;
    P0 = 0.  0.; 
    P1 = 5.  0.;
    P2 = 10. 0.;
    D1 = DROI 5  P0 P1;
    D2 = DROI 5  P1 P2;
    MAI1 = TRAN (D1 ET D2) 5 (0.  5.);
    MAI2 = TRAN (D1 ET D2) 5 (0. -5.);
    DED1  DED2 = DEDOUBLE (MAI1 ET MAI2) D1;
