Optimization constraints

Hello,

I have tried running a topology optimization on a simply supported beam. I defined the objective as min. mass but did not introduce any stress or deformation constraints. And the optimization gave results. Is it possible to run a topology optimization without constraints? Then based on which parameter the software optimizes the structure, does it automatically introduce constraints by itself?

Thank you,

Muge Candogan

Hi @Muge Candogan

Yes, you can have a setup without constraints. But the probability of 100% design material removal is high without a constraint.

Hello Prakash, thank you for your response. I am wondering based on which parameter the software optimizes the geometry, if I don't have any constraints.

Thanks,

@Muge Candogan

Solver will search whether the constraint is active or not and moves ahead with optimization based on Gradient based optimization.

Maybe this chapter on Optimization guide Ebook will answer your question /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>
