The Université Bretagne Sud has developed an algorithm in order to improve fusion plasma simulation (gyrokinetic and kinetic codes, turbulent transport) and especially reached problems of convergence of two-scale models. This project gave the way to transfer information between the various scales while attending simulating a multi-scale phenomenon. Conveniently used to tackle many phenomena involving oscillations or heterogeneities with high degree of accuracy, yet without requiring detailed input, this technology can find many applications in the study of complex fluidics, porous media flow and oscillatory dynamical systems.
