  The plasma response to Resonant Magnetic Perturbations (RMPs) in ASDEX
Upgrade is modeled with the non-linear resistive MHD code JOREK, using input
profiles that match those of the experiments as closely as possible. The RMP
configuration for which Edge Localized Modes are best mitigated in experiments
is related to the largest edge kink response observed near the X-point in
modeling. On the edge resonant surfaces $q = m/n$, the coupling between the m +
2 kink component and the m resonant component is found to induce the
amplification of the resonant magnetic perturbation. The ergodicity and the
3D-displacement near the X-point induced by the resonant amplification can only
partly explain the density pumpout observed in experiments.
