I suppose it depends on your definition of "rigid."  If you want bonds to be 
kept rigid, use constraints.  If you don't want the CNT to move, then use 
position restraints to keep its position (mostly) immobile.

Other types of angle and dihedral restraints are explained in the manual and on 
the Gromacs website.
