DESIGN SPACE - EXOSKELETON

Nancy Jewel Mcdonie

Hi all, 

I'm doing a task with Exoskeleton Design Space, with Design variables: Topology (Figure 1). HyperMesh will inllustrate the newly generated exoskeleton (1D elements) (Figure 2) - represented by CBEAM elements with beamsection as shown in figure 3. After I run the optimization,  I can define where structure need to reinforce (Figure 4) (to not eceexed the optimization constraint). The question is, can I run a size optimization (after topology optimization) for these beams in figure 4? 

Thanks for your reading

Hello @Lương Ngọc Lâm ,

 

this should be possible, but it is not part of the workflow in the exoskeleton context. The exoskeleton context will set up a model to perform either topology OR size. It doesn’t apply the size variables to a pre-run topology result (hopefully that makes sense).

This could be scripted, or, you could simply take the result from the topology and use those local regions to create new CBEAM’s and then perform size.

For such an approach, we would create size variables around the whole model and then delete the large majority we don’t want leaving only the isolated results as per image #4 in your message – that would be the quickest way but maybe not be the most accurate if you want the exact same position of the topology CBEAM and size CBEAM.

 

Hope this helps,

Michael
