The first version was developed for educational purposes and was published in a [handbook](https://www.colibri.udelar.edu.uy/jspui/bitstream/20.500.12008/22106/1/Bazzano_P%c3%a9rezZerpa_Introducci%c3%b3n_al_An%c3%a1lisis_No_Lineal_de_Estructuras_2017.pdf) of the course _Análisis no lineal de Estructuras_ taught at [Facultad de Ingeniería](https://www.fing.edu.uy/), Universidad de la República since 2017.\n\n## Some examples\n\n### A deployable ring\n![ring](https://github.com/ONSAS/ONSAS/blob/master/docs/src/assets/deployableRing.gif?raw=true)\n\n### A propeller model\n![propeller](https://github.com/ONSAS/ONSAS/blob/master/docs/src/assets/propeller.gif?raw=true)\n\n### A truss tower model\n![tower](https://github.com/ONSAS/ONSAS_docs/blob/master/gifs/tower.gif?raw=true)\n\n\n## Contact \u003ca name=\"connect\"\u003e\u003c/a\u003e\n\nYou can send an e-mail to _jorgepz [AT] fing.edu.uy_ .\n\n## License\n\nThe code is distributed under a GNU-GPL 3.0 license.\n\n## How to use ONSAS \u003ca name=\"howtouseonsas\"\u003e\u003c/a\u003e\n\nThe user should follow these steps to install and run onsas:\n\n1. Download and install [GNU-Octave](https://www.gnu.org/software/octave/) and [Paraview](https://www.paraview.org/)\n1. Download the ONSAS zip source files from the realeases web https://github.com/ONSAS/ONSAS/releases\n1. Open GNU-Octave, move to the _examples_ directory and run one of the examples.\n\nAn introduction to using and contributing to ONSAS was presented in 2022. The recording is available at [this youtube video](https://www.youtube.com/watch?v=tkJAD4UDvfI).\n\n## Contributions \u003ca name=\"contributions\"\u003e\u003c/a\u003e\n\nThe complete list of authors of code, contributions, affiliations and acknowledgments is available [in the documentation](https://onsas.github.io/ONSAS/dev/#Authors).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fonsas%2Fonsas","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fonsas%2Fonsas","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fonsas%2Fonsas/lists"}
