Relative motion of two or more bodies to each other is an unsteady problem of fluid dynamics. The area of the solution is discretised by several gridblocks which overlap. This technique is called chimeratechnique. For numerical solution of the two-dimensional Euler equations an Upwind-scheme is used. The grids, which undergo rigid-body motions, are created by Poisson mesh generator. First, basic research on shocks in the overlaping region is done. The one-block solution is the reference. The pressure-, lift- and moment-distributions are compared for both cases. Finally a separation of two bodies of a hypersonic vehicle and the passing of two bodies (NACA 0012-airfoils) in a tunnel are calculated.
