An adequate modeling of the electromagnetic interaction of a magnetized plasma with the surrounding machine’s conductors is paramount for the correct replication of 3D plasma dynamics. Reproductions of the latter provide useful predictions regarding the evolution of MHD modes and the electromagnetic forces acting on the vacuum vessel when said modes trigger disruptions. The here presented modeling efforts involving the 3D FEM non-linear MHD code JOREK have accomplished the self-consistent coupling of eddy currents in a full MHD physics scenario, with the related validation and simulation, employing the wall code STARWALL. This contribution also features the latest progress concerning the self-consistent coupling of halo currents (which flow from the plasma to the wall and viceversa) with the 3D wall code CARIDDI; this is essential for the prediction of the related rotating sideways forces that could pose a serious threat to future machines.
