  By exploiting the nonlinear amplification of the power deposition of RF
waves, current condensation promises new pathways to the stabilisation of
magnetic islands. We present a numerical analysis of current condensation,
coupling a geometrical optics treatment of wave propagation and damping to a
thermal diffusion equation solver in the island. Taking into account the island
geometry and relativistic damping, previous analytical theory can be made more
precise and specific scenarios can be realistically predicted. With this more
precise description, bifurcations and associated hysteresis effects could be
obtained in an ITER-like scenario at realistic parameter values. Moreover, it
is shown that dynamically varying the RF wave launching angles can lead to
hysteresis and help to avoid the nonlinear shadowing effect.
