This repository contains code of the following paper:
Changyu Deng, Yizhou Wang, Can Qin, Yun Fu, and Wei Lu. "Self-Directed Online Machine Learning for Topology Optimization." arXiv preprint arXiv: 2002.01927 (2020) Download
We are still working on the manuscript. More code and results will be uploaded soon.
Open an issue for this repository or send emails to dengcy@umich.edu. I will try to respond within a few hours. Pull requests are welcome.
There are 8 examples of 4 types in the paper, two compliance minimization problems (coarse mesh/fine mesh), two
fluid-structure optimization problems (coarse mesh/fine mesh), a heat transfer enhancement problem (heat)
and three truss optimization problems (truss). Their code is in their individual folders; they do not share files. Please refer to
the readme.md file in their own folder for more specific info.
Following softwares are used:
- COMSOL Multiphysics 5.4
- Matlab 2019b
- Python 3.7
- PyTorch 1.2.0
Higher versions should work fine. Lower versions may be compatible. Refer to the folders for more details. Some additional packages may be needed.
Please note that the reproducibility is not guranteed due to PyTorch platform (see its documentation), yet similar results are expected.
2021-09-04 Uploaded all examples. More comments and instructions for the truss problems will be added later.
2021-09-03 Fixed some issues in existing examples to match the paper. New examples will be uploaded soon.
