    Description :
    _____________

    Some situations imply the creation of elements whose nodes 
 merge in space. It may seem interesting to the user to replace 
 them with elements for which the double nodes appear only once,
 for instance triangle for quadrangle, prism for cube.

    There are two stages in this process :

 First the nodes must be merged by means of the ELIMINATION operator,
 then the elements containing them must be transformed by means of 
 the REGENERER operator.

    Contents :
    __________

    GEO2 : geometry to be regenerated (MAILLAGE type)

    GEO1 : generated geometry (MAILLAGE type)
    
    VERI : keyword indicating that the final mesh must be verified
           for non double nodes (warning if there are some)

    Example :
    _________

    OPTI  ELEM QUA4 DIME 2;
    POIN1 = 0 0 ; POIN2 = 5 0;
    LIG1  =  POIN1 DROI 5 POIN2;
    SURF1 = LIG1 ROTA 5 90.  ( 0.001 0.) ;
    ELIM SURF1 0.05 ;
    TRIQUA1 = REGENERER SURF1 ;
