Synergetic effects involving transport and radiofrequency (RF) heating in fusion confinement devices are important if regions of phase space that contain poorly confined particles are populated by the use of auxiliary heating. Such poorly confined particles include ripple trapped particles in tokamaks and stellarators or transitional and high energy passing particles in bumpy tori. A two-dimensional, steady state Fokker-Planck code has been developed to study the interaction of these processes and it has been used to model the Elmo Bumpy Torus (EBT). Accurate modelling of the RF absorption profile in real space is shown to be of critical importance for the simulation of EBT, and a comparison of the results of the model with experimental data shows very good agreement. Extension of the model to closed-field-line configurations with straight 'bumpy' sections connected with high magnetic field corners shows reduced synergetic effects and greatly improved performance compared with bumpy tori.
