In order to use this repo as a python package, you need to add /struct_opt_benchmarks in $PYTHONPATH

The work flow using this repo to solve topology optimization problems will be:

1. Use preprocessors/preproc.py to generate a .pkl file that contains the description of entire problem, including geometry, mesh, load and boundary condition. Run preproc.py --help to see all options. Note that tmr needs to be installed in order to generate unstructured mesh. Please refer to tmr document for more information: https://smdogroup.github.io/tmr/.

2. Execute optproblems/optimize.py with the problem pkl file to run optimizations. Run optimize.py --help to see all options, including all supported optimization problems, optimizer settings, etc.

3. Use utility functions in utils/ to postprocess results.
