  H phase space painting using charge-exchange has been used in synchrotrons to inject and accumulate high intensity bunches of protons, but has never been used in Fixed Field Accelerators (FFAs). In H charge-exchange injection, H ions pass through a thin foil where the electrons are stripped from the ion leaving a proton. In combination with an appropriate dipole, well-separated H ion and proton beams converge at the foil in this non-Liouvillean process. This can be combined with painting of the phase space, where the position of the injected beam is manipulated with respect to the circulating protons in order to inject beams having a specific profile in phase-space. In this paper the simulation of such injection is studied, performed using the latest improvements in the OPAL code. Injection into a small test ring that is under development as part of the ISIS upgrade program is considered.
