Abstract

This paper presents an efficient parallel-distributed methodology for solving multiphysics problems. A functional decomposition of the global problem is used first followed by the classical geometrical decomposition . Several technical details are presented for more clarity and for easing its implementation. All the techniques discussed in this paper are illustrated for a CFD-based aero elasticity simulation. A thorough performance study is shown with simulation results for the aeroelastic AGARD 445.6 and the turbulent flow over the ONERA M6 wing.
