Simulation Analysis of Fluid-Structure Interactions with Moving Mesh

This paper demonstrates techniques for modeling fluid-structure interactions with moving mesh in COMSOL Multiphysics. It illustrates how fluid flow can deform surrounding structures and how to solve for the flow in a continuously deforming geometry using the arbitrary Lagrangian-Eulerian (ALE) technique. The ALE method handles the dynamics of the deforming geometry and the moving boundaries with a moving grid.
