Optistruct- Is it possible to optimize a shape and then run a stress analysis test on it?

Hi,

I want to see the difference in the stress analysis results between: a shape that is being constrained by a mass and has minimum compliance VS a shape that has a minimum volume fraction and has a stress constraint (using the DTPL card to set it).

When I choose the analysis option in optistruct I get the exact same analysis results for both shapes (even thought when I choose optimization option they turn out different).

How can I get two different stress analysis results?

Better question: Is it possible to optimize a shape and then run a stress analysis test on it?

    Is it possible to export the densities of elements in the mesh after the shape is optimized, then import it into a new file in Optistruct so I can use the analysis tool on these elements in order to find the stress results? (Can I export the optimization result --> then analyze it?)

    Hi,

     

    You can actually use OSSmooth with Re-analysis option ON to map the loads and BCs to the optimized model automatically.
