Hello,
I am wondering the exact theorical methodology used for Lattice optimization and topology optimization. Let me explain in detail. When I check topology optimization and OptiStruct Guides, they always say The SIMP method is used to conduct topology and lattice optimization problems.
I am looking for references The SIMP method used in OptiStruct. When I checked different articles, I see that there could be some modifications on SIMP method to prevent checkerboard effect. For instance, when MINDIM, MAXDIM are defined in topology optimization, what kind of filter is implemented ( density or sensitivity etc.) ?
In articles, modified SIMP approach is mentioned to get rid of singularity as well. Is modified SIMP approach used in Optistruct algorithm or does it use different methodolgy to ban singularities ?
Thank you for your answers
Best Regards
