The numerical analysis of aerodynamic flows is in general limited to steady geometries. Depending on the flow conditions steady or transient flow solutions in the relative frame of the body are computed. In order to take into account the flexibility of the body (e.g. fluttering wing) and the motion of the body (manoeuvre flight), moving computational meshes are required. The CFD method has to take into account meshes with moving nodes and deforming control volumes. The present paper shows computational results of different applications with moving grids, e.g. an oscillating airfoil, a fluttering wing and a guided manoeuvre flight of an airplane.
