Interactive topology optimization for compliant mechanisms — unleash your creativity!
TopoptComec helps you design compliant mechanisms — flexible structures that achieve motion through material deformation rather than joints.
Simply draw your domain, set forces and supports, choose your material and optimizer, then watch the algorithm sculpt the optimal shape — in 2D or 3D.
None of the existing competing solutions combine all of these features in a single tool:
- 🔨 Rigid structure and compliant mechanism — Same solver, just change the loads.
- 🧊 2D and 3D support — Real engineering isn’t flat.
- 🚀 Fast, like really fast — Designed for performance, not academic demos.
- 🧪 Flexible — Tons of parameters to tweak → infinite design possibilities.
- 🛡️ Reliable — Bugs fear this program.
- 🍰 Easy to use — Intuitive GUI and CLI, piece of cake to use.
- 🔓 Open source — Transparent, extensible. No black boxes.
git clone https://github.com/ninja7V/topoptcomec.git
cd topoptcomecpip install -r requirements.txtGUI:
python main.pyCLI:
python main.py -p ForceInverter_2Sup_2DTweak the parameters or choose a preset and hit "Create"!
Once you’re happy with your mechanism, export it for visualization in ParaView or for refinement in your favorite CAD software.
The interface should feel intuitive, but you’ll find detailed visual explanations in the Wiki.
Ideas, bug reports, or pull requests — all are welcome. Let’s build something awesome together!

Thank you for using TopoptComec 🙂
Just optimize!
