Abstract We present here results of visco-resistive 3D MHD numerical modelling aiming at clarifying the mechanism responsible for the stimulated helical organization observed in experiments. Preliminary results [7] indicate that the degree of helical order is actually modulated in amplitude and in particular amplifyied according to the oscillation imposed by the applied boundary condition representative of the experimental action. The conditions for chaos healing and the ensuing effect on test particle transport in terms of the MHD mode spectrum are also being investigated.
