We present a numerical modelling of the interaction between a quiescentfilament and a large-scale shock wavefront passage. Large-scale coronalwaves can perturb distant quiescent filaments, and they might force theireruptions. E.g., after the occurrence of a Moreton event, some observations have reported sudden oscillations -in spatial displacement and intensity emitted by winking filaments. Also, observations have led to the conclusion that winking filaments are generally coincident with the wavefront passage of the Moreton coronal counterpart. However, observations have failed to detect the perturbing large-scale wave interaction with the filament at a coronal level; which have generally been estimated by indirect methods.
