The research is a cooperation with researchers at california institute of technology, and will pioneer superfluid flow structure interactions with are of key importance in technological and astronomical applications. This chapter describes the immersed membrane method imm and the fluid structure interaction solution strategy on unstructured meshes 1. These methods, which typically use an eulerian description of the fluid and a lagrangian description of the structure, can treat thin immersed boundaries and volumetric bodies, and they can model. The ib formulation of such problems uses an eulerian description of the fluid and a lagrangian description of the structure. It will be of special value to researchers and engineers as well as graduate students working on immersed boundary methods, specifically on recent developments and applications. On the boundaries, the standard boundary conditions for the navierstokes equations are. It does this by adding a body force term in the momentum equations. In the context of partitioned solvers, a finitedifference flow solver is coupled with an isogeometric analysis tool for thin shells, with the aim of providing numerical accuracy for moderate reynolds numbers fsi. Fluid structure interactions can be stable or oscillatory. Immersed methods provide mathematical and computational frameworks for modeling fluid structure systems.
