    Hi Mohamed,

    Signed VonMises in Expresseion Builder is supported in HyperView 2017.2 version.

    I recommend you to update to the latest HyperWorks version.

    Hi Mohamed,

    I didn't understand on 'alternating stress'. Can you please elaborate more on this.

    Hi Mohamed,

    I think this is possible only through expression builder.

    I'll check into this and will update you if any workaround is possible.
