Simulation of fluid-structure interaction using patched-overset grids

The simulation of dynamic fluid-structure interaction has historically pres ented several challenges when computed on patched grid systems. Traditional ly, the structures are static or constrained to predefined motions, as with a piston. However, overset grid methods, in the context of patched grid sy stems, provide a vehicle for simulating truly dynamic fluid-structure respo nse and interaction for geometrically complex objects. Presented here is a new method for the simulation of dynamic fluid-structure interaction based on patched-overset grid systems, which allows for the coupled dynamics of t he problem to define the movement of fluid and structure.
