Hello! Does anyone have any clue why my model might be flying off into space every time I apply a load on it? I'm using inertia relief (-2) so I'm not sure as to why this is happening. 

Any advice would be much much appreciated!

    Hi Shindy,

    One of possible causes: some parts/elements were not connected well. 

    To find those parts/elements, you can run a free-free modal analysis(use 0.0Hz as lower boundary of Eigenvalue range) and check the animation, if it's connected well it should have clean 6 rigid body modes. 

     

    Thanks.
