The objectives of this Large scale initiative are twofold at least. The first objective for which the four year length of the proposal should be adequate is to develop specific numerical tools tailored for the specific simulation needs of the physicists working on magnetic fusion in general and ITER more specifically. Most of the research axes developed in this proposal are oriented towards this goal and imply essentially teams that are already active in the fields.
A more long term objective that is sought is to increase the implication of the applied mathematics and computer science community in research linked to problems posed around ITER. There is no doubt that from the stronger implication of mathematicians and computer scientists in the field, new more fundamental open problems in mathematics and computer science will emerge for which ITER will be an challenging application. To this purpose, summer schools and workshops on magnetic fusion specifically targeting the applied mathematics and computer science community will be organized. This should help a new community with the technical background and skills that will be needed to tackle the numerous challenges linked to modeling and numerical simulation that remain on the path to controlled magnetic fusion.
Specifically, the Toulouse team is responsible of the development of novel numerical techniques for the large scale simulation of plasma turbulence in Tokamak. These methods are based on the 'Asymptotic-Preserving' schemes methodology applied to highly magnetized plasmas. See more detailed desciption here.
