Fluid-Structure Interaction

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 webinar will show how to simulate FSI, explore characteristic examples, and demonstrate how to solve such a problem in COMSOL Multiphysics. The demonstration features 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 concludes with a Q&A session.
