Hi,

i have just started using the hyperworks desktop application. I am trying to rebuild the example illustrated in the startet kit videos. Thus i created a part in catia and saved it as an iges-file. After that i performed the steps shown in the tutorial, but when i load the h3d-file the result looks nothing like it should. It is just a flat, 2d surface, that looks broken(?)

I habe uploaded three pictures to show you what i mean

    Hi Sebastian,

    From the hyperview screenshot shared,

    I might not be about to tell you exactly what might be the issue,

    but from the image,

    you can rerun the model with a small load, compared to the load applied now,

    else the material properties needs to be rechecked,

    the Modulus especially.

    Also the 1D elements used, are they RBE2??

    Cheers!!

    from the image I can conclude that you have constrained the model in only translation of all direction i.e. 123 but I guess you have to constained the model also in rotatonal direction of axis about which it will rotate.( If axis of rotation of bolt is X then please constrain 4 also).

    Ok just solved it. I had to recreate the constraints. They were broken (perhaps after remashing?)

    Thanks
