-excerpt: Magnetically confined fusion plasmas are being designed within the International Tokamak Experimental Reactor (ITER) and other projects that will operate in physics regimes only recently achieved through experiment. Modeling and simulation activities are required to design and optimize these new facilities. The fusion community is developing an approach to whole device modeling that will provide predictive numerical simulations of the physics required for magnetically confined fusion plasmas to enable design optimization and fill in the experimental gaps for ITER and future fusion devices.
