The oscillatory power and particle exhaust in magnetic fusion devices with high confinement (ELMy H-mode) exhibits a strong link between core and edge plasma with the Scrape-Off-Layer (SOL). Generically, the latter acts in a twofold way since it removes power and particles away from the upstream region but it also refuels the core and edge via interaction with the vessel. Thus, any modelling attempt to provide a consistent picture of the transients has to account for the prevailing transport processes and time-scales of the core and the SOL including the neutrals. The integrated transport code COCONUT combines the 1.5D core code JETTO with the 2D SOL code EDGE2D with the separatrix as communicative layer exchanging fluxes between the codes. Previous results of Type-I ELM simulations indicate a strong influence of neutral dynamics on refuelling the edge since it actively affects the ratio of convective to conductive losses from the edge and thus the building up of the pressure gradient within the ETB.
