Is it possible to do topology optimization with JuMP.jl?

Specific Domains Optimization (Mathematical)

Hello everyone! I would like to know if it is possible to do topology optimization with JuMP.jl? For topology optimization problems the stiffness matrix changes in each step, could this be formulated in JuMP.jl? In the tutorial, it seems only a fixed stiffness matrix can be provided into the model.

Which tutorial? There’s nothing in JuMP specifically for topology optimization; you’d need to implement the relevant optimization problem, although you might first want to read Should you use JuMP? · JuMP

Have you seen: GitHub - JuliaTopOpt/TopOpt.jl: A package for binary and continuous, single and multi-material, truss and continuum, 2D and 3D topology optimization on unstructured meshes using automatic differentiation in Julia.?

Thanks for your suggestion! I did not realize this before.

I have noticed this package before. But currently I want to use new methods which are not include in this package.

I would advise you visit topopt Slack channel (It is one of the main Julia Slack channels) and talk directly to the dev. They are very responsive and helpful from my experience.

Hi!

I am the maintainer of TopOpt.jl, happy to chat about your application and how to best make use of existing functionality in TopOpt.jl so you don’t have to re-implement everything from scratch :slight_smile:
