The symbol Γ represents boundary conditions with the subscripts s and f referencing the solid and fluid boundaries, respectively. The Fluid and Structural Domainsįigure 49 presents a schematic of a discretized computational domain with fluid occupying space ( Ω f) and solid body occupying space ( Ω s). This maturity was necessary before the coupling of CFD and CSM software could be expected to be successful. In addition, moving and morphing mesh capabilities in CFD software needed to solve FSI problems have only recently matured to the point at which they can be reliably used. While there has been an interest in solving FSI problems for decades, large computer clusters capable of solving them for full scale systems have only become widely available to engineers in the past decade. COUPLING METHODOLOGIES FOR SOLVING FSI PROBLEMS (10) Readers interested in more information should consult that reference. This information is taken from Bojanowski et al. This appendix provides details of the coupling and verification for the FSI solutions used in this study.
