In the domain of Edge-Localised-Modes, validation of the JOREK code has been achieved by addressing various characteristics of this instability. The necessity to control ELMs, in order to reduce divertor heat-fluxes in ITER, while maximising the flushing of high-Z impurities, motivates a thorough validation of the numerical and physical model, so that reliable predictions can be provided for future devices. With increasing concordance between simulation results and experimental observations, non-linear MHD is starting to provide insight into several open questions about ELM physics and ELM-control techniques, in time for the development and exploitation of ITER operation.}, publisher = {International Atomic Energy Agency, Vienna}, title = {ELM and ELM-control Simulations}, year = {2019} }
