Abstract
The study of a system of continuous spins on a frustrated triangular l attice evolving as a cellular automaton is presented. Initially disord ered lattices are seen to organize into modulated patterns. It is show n that frustration on the triangular lattice is not a sufficient condi tion for the appearance of an incommensurate modulation; anisotropy, w hich breaks the hexagonal symmetry, must also be introduced. There is a critical value beta(c) for the anisotropy above which the incommensu rability is found.
