    -------------   
    RIG1 = XXT CH1 (FLOT2);
    

 
    Description :
    _____________
 
    The XXT operator calculates the matrix RIG3 (RIGIDITE type) 
 associated to the tensorial product of the field by points CH1 
 (CHPOINT type) by itself. This product can be pondered by FLOT2 
 (FLOTTANT type).
 
    Note :
    ________
 
 -  The mesh which supports RIG1 is formed by one superelement collecting
    all the nodes underlying CH1.

 -  In order not to disturb the behaviour of the RESO operator (linear
    system solver), CH1 should be formed of only one zone, and its 
    components should be homogeneous to forces (see the manual of the
    FORC operator).
 
 -  The subtype of RIG1 is 'RIGIDITE'.
