A Distributed Computing-Based Methodology for Computational Nonlinear Aeroelasticity

This paper. highlights some technical,features of an analysis methodology being developed for nonlinear computational aeroelasticity. After a brief overview of classical linear and non-linear computational approaches for aeroelasticity, we address the problem of satisfying the Conservation Law for dynamic meshes. A conservative finite element formulation for the coupled fluid/mesh interaction problem is proposed. Fluid-structure conservative finite element formulation for the coupled fluid/Mesh coupling algorithms are then discussed with some emphasis on distributed computing strategies. Preliminary numerical results are finally shown.
