In the materials processing industries, it is often desired to compute the stress and deflection in polymer or aluminum extrusion dies. Many thin film coating processes, such as roll coating and blade coating, involve deformable materials and components. Web flotation and tape transport systems include thin flexible membranes moving through air. The deformation and f low-induced vibration of slender structures can be very important in applications such as tube bundles, marine risers, and antennas. It solves for the linear and non-linear elastic response of the solid.
Problems can be steady or unsteady.
Postprocessing of the deformed structure, stresses, strains, and forces is provided. Vibrations of a flexible beam are caused by vortices shed from the square cylinder as air flows from left to right. FSI problems can be solved at different levels of complexity. For simple problems, where the deflection of the structure is small, the coupling between fluid and structure is weak and the two calculations can actually be accomplished in separate steps. A classic example of such a strongly coupled system is flow-induced vibration.
