Parametric shape optimization with differentiable FEM simulation
- conorbergin 1y agoInteresting that you talk about using shape optimization leading to more manufactureable results than a continuum approach. What sort of manufacturing do you envision, welded tube frames, cast parts? The weird organic results you get from the free form simulations are often pretty easy to 3d print with something like SLS, as long as they don't have voids and thin features. The constraints on other manufacturing methods are a lot more complex.

- essexedwards 1y agoAccording to the paper (https://arxiv.org/abs/2411.19421 https://arxiv.org/abs/2411.19421) the code for SiMPL is implemented in MFEM and is available here: https://github.com/dohyun-cse/mfem/tree/simpl2 https://github.com/dohyun-cse/mfem/tree/simpl2.
- gsf_emergency_2 1y agoSeems like that's a fork of mfem, I don't see simpl-specific code? To be released later? It's "Matlab style" c++, less uh accessible than jax heh
- essexedwards 1y agoI haven't read the code, but I would expect simpl.cpp to have something to do with SiMPL https://github.com/dohyun-cse/mfem/blob/simpl2/miniapps/simpl/simpl.cpp https://github.com/dohyun-cse/mfem/blob/simpl2/miniapps/simp...
- gsf_emergency_2 1y agoThank you! Sorry! Note to self- always check the branches carefully so i don't look like an ass
