A multiblock Reynolds-Averaged Navier-Stokes method has been used in conjunction with a chimera domain decomposition technique for the calculations of incompressible viscous flows around complex configurations with relative motion. The chimera method is used to connect embedded or patched grids together by interpolating information across the grid boundaries. A new conservation technique for grid interface was developed to maintain a smooth solution across the linking boundaries for unsteady flows with relative motion between the grids. The method has been employed for the prediction of unsteady flows around a cylinder undergoing large amplitude oscillations.
