Hi!

 

I have a question connected with topology optimization results. I optimized solid Design Space, but as the result I got shell structure  when I choosen equal values on the result panel. 

1) Could you please explain why is this shell and how Optistruct calculates mass in .out file in this case:  mass of solid or shell? 

2) What is the physical difference between element densities as 0.8 instead of 1?

    Hi @Ekaterina

     

    Can you try with a different constraint for optimization?

     

    Composite failure response will not work because the design variable is different
