     SURF2 = RAFT (CHPO1) SURF1 (N1);



    Description :
    ____________

    The RAFT operator divides the  size  of  the elements  of  an 
 existing triangular mesh until the wanted size is obtained.  The 
 size is localy given at each node of the mesh SURF1 (by a  CHPO1 
 object or by the local value). No node is added on the boundary,
 nodes are added in the interior in order to  obtain  the  wanted 
 size. The number of added nodes can be limited by N1 value.

    __________

    SURF1:  object of MAILLAGE type. It is  composed of triangles 
 exclusively.

    CHPO1: object of CHPOINT type.This field of point value gives 
 the local sizes. Each point is attributed to a node of SURF1 and 
 its value corresponds to the size (lenght)  of  the  elements at 
 the node. If CHPO1 is not given, the size is given  by the value 
 of density at each  node  of  SURF1 ( which is  computed  at its 
 creation).
    
    
    N1   : object of ENTIER type. It is  the  maximum  number  of 
 nodes the  resulting mesh can  have. It must be greater or equal 
 to the number of nodes of the existing mesh (SURF1).
   
 
    Note :
    ______

    The  RAFFINEUR  operator  doesn't  suppress  any  node of the 
 initial mesh (SURF1) even if the mesh is too dense in respect to 
 the wanted size (CHPO1).
    
 
    RAFT works only on linear elements: SURF1 must be composed of 
 TRI3 type SURF2 will be composed of TRI3 type.
