Computer simulations have been carried out to test the recently proposed model for the nanodomain structure of relaxor ferroelectrics such as lead zinc niobate (PZN). The present results confirm that 
and 
as well as the previously proposed 
types of Pb displacement are viable possibilities, but the number of domain boundaries required to produce sufficiently strong diffuse rods of scattering means that individual domains cannot be described as three-dimensional and must still be considered to be relatively thin plates.

A simple Monte Carlo model has been developed that convincingly reproduces the diffuse streaking that is observed on selected-area electron diffraction patterns of the rhombohedral phase of PZT. These results provide substantial evidence that the Pb as well as the Ti/Zr ions are displaced away from the centres of their coordination polydedra along cubic <111>c directions and that these displacements are correlated along chains that run along <111>c also.
