The resistive wall mode (RWM) is a macroscopic MHD instability that limits the fusion power production of advanced tokamaks. Realistic modeling of this mode often requires detailed 3D description of the conducting structures such as the surrounding resistive wall. We have developed a new code CarMa [1] by coupling the MHD stability code MARS-F [2] with the 3D finite element based eddy current code CARIDDI [3]. The coupling scheme is shown correct both analytically and numerically. Feedback stabilization of RWM is investigated for ITER advanced scenarios. \newline [1] R.
