Description
The ITER actuator controllers will need numerical test and tuning with a “tokamak simulator” based on 1.5MHD equilibrium/transport model, ideally during pre-shot operation.
Coupling the equilibrium code LIUQE and transport code RAPTOR, the fastest available to our knowledge in their categories, would provide a fast and control oriented simulator for this purpose.
A stable, flexible and fast numerical method to solve for the non-linear coupling is sought. The Jacobian Free Newton Krylov method is investigated in terms of stability against initial conditions and minimum number of evaluations of the non-linear function required.
