Description:     A Bird strike on rigid plate (as replacement for a composite 
                 inlet of jet engine) is modeled with a Lagrangian, ALE and SPH 
                 approach for the bird. This input deck serves as example to
                 provide consistent results among platforms and version of 
                 the code as well as between the different modeling approaches.
