Combined functional and geometrical decompositions for multiphysics problems with application to fluid-structure interaction

摘要

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 aeroelasticity 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.
