| Installation | The maker provides a pip installation command and an editable installation path for development. | The quick guide instructs users to install PySWMM with pip install pyswmm and lists Python 3.6 or higher, 64-bit x86-64, as a requirement. |
| Integrations | The API includes functions for importing GDS polygons and working with GDS layer stacks and ports. | The project describes PySWMM as an interface to USEPA SWMM5 and its repository lists PySWMM, SWMM-TOOLKIT, and SWMM5 as layered components. |
| Intended users | The project describes FDTDX as freely usable for research, development, and commercial work involving photonic nanostructures. | The project says it is used by engineers, modelers, and researchers working on stormwater modeling optimization, controls, and results post-processing. |
| Purpose | FDTDX is an open-source Python package for simulating and designing three-dimensional photonic nanostructures with the Finite-Difference Time-Domain method. | PySWMM provides Python access to the SWMM data model for stormwater modeling. |
| Support | The FAQ invites users to open GitHub discussions for unanswered questions and issues for suspected bugs, and says the maintainers regularly check discussions. | The project directs users with bugs or support questions to GitHub Discussions and its issue tracker. |
