Sur une stratégie de calcul pour les problèmes multiphysiques

Abstract : The aim of this work is to extend the usual concept of interface between substructures to that of interface between physics in order to propose a general framework for the simulation of multiphysic problems. A new strategy, derived from the latin method, is presented and its feasibility demonstrated on the fluid structure interaction problem in porous media. A technique of radial loading approximation of unknowns is then setup to increase the performance of the method. The following step is the use of the concept of interface between physics to take into account the time and the spac multiscale aspects. Techniques of coupling and transfer are introduced in order to allow the use of different time and space discretizations for each. Lastly, some works on the taking into account of the nonlinearities are presented, showing that these aspects do not affect the performance of the strategy.
