We develop a dynamic mesh adjustment scheme for moving boundary problems such as those encountered in fluid structure interaction. The scheme is implemented in an arbitrary Lagrangian Eulerian (ALE) flow solver for unstructured hybrid meshes and dual time-stepping for Navier Stokes problems. The mesh improvement strategy is an extension of our previous work on mesh optimization based on quality metrics. In the associated numerical experiments, we consider translation and rotation of a profile interior to the flow field. Numerical results for vortex shedding past the moving profile demonstrate the simulation capability and display the effects of dynamic mesh adjustment.
