Presents numerical simulations of two ICRF heating experiments in ASDEX, using the FISIC code to solve the integrodifferential wave equations in the finite Larmor radius (FLR) approximation in fully toroidal geometry. The results of the FISIC code are compared with those of a plane-stratified model and of ray tracing. The different models show on the whole good agreement; the authors can however identify a few interesting toroidal effects, in particular on the efficiency of mode conversion and on the propagation of ion Bernstein waves.
