Overview
ABSTRACT
Most domain decomposition methods which are currently used in all engineering sectors encounter, due to their decomposition in a large number of sub-domains, problems of insufficiently parallelized resolution problems. Furthermore, raising the iteration number lowers the calculation speed and convergence diminishes. In order to solve these problems and to obtain scalable methods, adding components such as the coarse grid or recoursing to time and space resolutions, notably with the parareal algorithm, can be used to obtain satisfactory solutions even within extremely complex contexts.
