Abstract
An innovative structural boundary element method (BEM) solver is developed for interfacing the computational fluid dynamics (CFD) and computational structural dynamics (CSD) grids. Formulated as a solid mechanics problem with a minimum strain energy requirement, the BEM solver generates a truly three-dimensional universal spline matrix. The universal spline matrix is a vector operator that includes the coupling of displacements and forces along all axes. Based on a similar formulation, an exterior BEM solver is also developed to account for the flowfield grid deformation. Thus, the BEM solver allows a unified treatment of the displacement and force transformation for CFD/CSD interfacing, as well as the computation of the flowfield grid deformation. The solution procedure is fully automated, and no additional model generation is required; therefore, is ideally suitable for computational aeroelasticity and multidisciplinary optimization applications.
