This paper addresses a methodology for designing PC clusters using object-oriented technology. The proposed methodology simplifies the design process and manages specification differences in both the academic and the industrial environments. This is to respond to the need to implement an existing CFD code on PC clusters for research purposes and future industrial usage. The objectoriented technology is well suited to solve this kind of design problems.

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.
