# sectionproperties
[](https://travis-ci.com/robbievanleeuwen/section-properties) [](https://sectionproperties.readthedocs.io/en/latest/?badge=latest)
a python package for the analysis of arbitrary cross-sections using the finite element method written by Robbie van Leeuwen. *sectionproperties* can be used to determine section properties to be used in structural design and visualise cross-sectional stresses resulting from combinations of applied forces and bending moments.
## Installation:
For more detailed installation instructions, refer to the [documentation](https://sectionproperties.readthedocs.io/).
### UNIX (MacOS/Linux):
```
$ pip install sectionproperties
```
### Windows
Install *meshpy* by downloading the appropriate [installation wheel](https://www.lfd.uci.edu/~gohlke/pythonlibs/#meshpy).
Navigate to the location of the downloaded wheel and install using pip:
```
$ cd Downloads
$ pip install MeshPy‑2018.2.1‑cp36‑cp36m‑win_amd64.whl
```
Once *meshpy* has been installed, *sectionproperties* can be installed:
```
$ pip install sectionproperties
```
## Documentation:
*sectionproperties* has a fully documented python API which you can find at [https://sectionproperties.readthedocs.io/](https://sectionproperties.readthedocs.io/). To read more about the theory behind the program, its implementation and some more examples, check out my blog at [https://robbievanleeuwen.github.io/](https://robbievanleeuwen.github.io/).
