Project

The FreeFem++ platform has been developed to facilitate teaching and basic research through prototyping. For the moment this platform is restricted to the numerical simulations of problems which admit a variational formulation. On the other hand, the development of new, simple but nevertheless efficient numerical methods is required to foster basic research for the numerical simulation of plasma in the context of the ITER project. Our goal is to evaluate the FreeFem tool on basic magnetic equations arising in Fusion Plasma.
