Hi Bailey, Thank you for your response! Yes - I totally agree with you. I have been using tosca with ABAQUS and getting great results. I am sure that developing a code to do that will take way longer time.
I am still interested in learning the math behind the theory, for the sake of learning as well as potential (very) application-specific optimizations once I learn well enough. I was thinking that implementing SIMP on my own is a great starting point, but figured that if someone did it with libmesh already it'd be nicer to know. :) Best, Shawn On Tue, Jan 22, 2019 at 10:58 AM Bailey Curzadd <bcurza...@gmail.com> wrote: > Hi Shawn, > > Minimum compliance optimizations and, to some extent, stress-based > optimizations of static structures are so well studied that developing > libmesh code to solve those problems is a bit excessive.
