Custom output definition

Good morning,

I am analyzing a model of a frame and I would like to output directly the stiffness of the frame in bending and torsion. I am currently running the analysis, postprocessing with Hyperview and retrieving the z displacement for the node of interest and successively using a spreadsheet I am performing the stiffness calculation.

Is there a more effective method to have this simple calculation already done by Hyperworks? Is there a way to have directly the displacement output for a specific node without the need to query it in Hyperview?

Thanks in advance

    Thank you,

    Currently, I can't use compose, in any case, is it possible to have the output just for one load-step and possibly just the vertical displacement?
    I have tried some solutions through the optimization panel by setting a response but since I am not running an actual optimization I can not display the response

    Thanks in advance for your suggestions

    using OPTI format you can ask this result for a particular LoadCase, under OUTPUT.

    But it will always give you all displacement components.

    As far as optimization, you can just run a 'zero' iteration optimization, and you can get these values outputted, including the math for stiffness if you know yhow to work with function DRESP2.

    If you to optimization >> opti control, you can define the DESMAX=0
