to chaos. Quasiperiodic route to chaos is observed for PM = 0.5. Note however that the bifurcation diagrams exhibits many other chaotic states whose origin could be through other routes of chaos. The geometry and the forcing function of the TG dynamo simulationsare simpler than those of experiments, and geodynamo and solar dynamo. Yet the similarities between the experimental results and the numerical simulations of Yadav et al. [10, 13] may be due to certain inherent common features of dynamo, e.g., nonlinear interactions among the large-scale MHD modes. Future numerical simulations with more realistic geometry and forcing functions will reveal valuable insights into this puzzle.
