The physics governing magnetic plasma confinement in tokamaks involves complex interacting nonlinear processes spanning disparate temporal and spatial scales, and as a result their computational modelling is challenging. In this talk we present a mathematical formulation and a numerical algorithm suitable for the three-dimensional simulation of the complete plasma field (from core to the first wall, including the edge and scrape off layer) and its electromagnetic interaction with the first wall. We then employ the algorithm to study transient magnetohydrodynamic events (edge localized modes and vertical displacements). The study reveals gaps in the underlying mathematical knowledge which will benefit from a synergy between continuum- and atomic-scale computational physics.
