I am working with some system, where one parameter 'A' (say) is periodically forced (that is the parameter varies periodically with time). I want to get bifurcation with other parameter 'B' (say). What I am doing:

1. I am running with amplitude =0 of the parameter 'A', which converges to a equilibrium.
2. I am taking now the last point, and continuing the equilibrium with amplitude=0.2 of 'A' and continue for the parameter 'B'.

It gives'No convergence at x0'.

However, if I run the model for same parameter setup, it runs well and shows period doubling time series at some value of 'B'. Just continuation for all 'B' values is not working.

Any idea, why it is doing so or how I can go through?
