Due to limitations for complex formulas, images and references in .rst files, some (small) details are only available in theDoc.pdf, see the github page of Exudyn! There may also be some conversion errors in the auto-generated html pages.

For license, see LICENSE.txt in the root github folder on github!

In addition to the tutorial in the documentation, many ( 250+ ) examples can be downloaded on github under main/pythonDev/Examples and main/pythonDev/TestModels . They are also on ReadTheDocs.

Note that ChatGPT and other large language models know Exudyn quite well. They are able to build parts of your code or even full models, see https://doi.org/10.1007/s11044-023-09962-0

Tutorial videos ( new Feb 2024 )can be found in the youtube channel of Exudyn !

Enjoy the Python library for multibody dynamics modeling, simulation, creating large scale systems, parameterized systems, component mode synthesis, optimization, …

For searching on Read the Docs (especially with the search preview), add * or ~1 / ~2 / … to your search to search more general, e.g., FEMinter* to search for FEMinterface, or objetfrf~3 to find ObjectFFRF. Your search preview usually finds less results than the search when pressing Enter. See also Read the Docs documentation
