Development of a parallel third order explicit multirate scheme
Résumé
Multirate schemes aims at circumventing the global stability restriction of classical explicit methods. The idea is to gather mesh elements in groups that satisfy local stability conditions. The transition between groups has to be accommodated to preserve convergence and conservation properties. The extension of these strategies to the parallel framework is challenging since the computational load varies at each stage of the algorithm. Here we focus on the parallel implementation of a third order multirate strategy for discontinuous Galerkin simulations.
