Design of efficient partitioned procedures for the transient solution of aeroelastic problems. (English) Zbl 1003.74081

Summary: We consider the problem of solving large-scale nonlinear dynamic aeroelasticity problems in time domain using a fluid-structure partitioned procedure. Our analysis is based on the estimation of energy that is artificially introduced at the fluid-structure interface by a staggering process that is inherent to most partitioned solution methods. Using two- and three-dimensional, transonic and supersonic, wing and panel aeroelastic applications, we validate this framework and highlight the selection of staggering algorithm for solution of coupled fluid-structure equations.
