Topology optimisation results to CAD model

Hello,

 

I am a student who is new to HyperWorks. I have been doing topology optimisation on a component and have got to a stage where I need to export the result as a CAD. My component was modelled as a shell element as it is very thin (1.27mm) and large in size. I have tried to use OSSmooth, however the resulting STEP file is not the optimised design. I have also tried Tools>>Export>> ISO SURFACE, but same outcome. Also I would like to export the design of not the final iteration but one in between. Could someone please suggest how I could get the result as a CAD file or suggest what I may be doing wrong?

 

Thank you in advance.

    Hi,

     

    Is there a reason for you to export an intermediate iteration ? (in most of the cases the optimization is not converged yet at this stage)

    However, for this particular case, one solution would be to show "iso plot" in HyperView and from this you can go in Tool/Export/Iso Surface

    BR-

    Also, if you run your optimization model and request the OUTPUT card as SHRES, you can control the generation of .sh files needed for OSSMOOTH.

    You could request it to be generated for ALL iterations.
