Fluid-Structure Interaction (FSI) is the interaction between a moving or deformable structure and an internal or surrounding fluid flow. Some examples include building sway, wing flutter, valve chatter, and cardiovascular blood flow. This COMSOL-hosted webinar showed how to simulate FSI, explored characteristic examples, and demonstrated how to solve such a problem in COMSOL Multiphysics. The demonstration featured a pull-in simulation of a MEMS switch accounting for contact and squeeze film damping where solid deformation and fluid flow are strongly coupled. The webinar concluded with a Q&A session.
