Multibody System Dynamics, Vol. 60, pp. 533-561, 2024. `https://doi.org/10.1007/s11044-023-09937-1 `_ 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! If you like using Exudyn, please add a *star* on github and follow us on `Twitter @RExudyn `_ ! In addition to the tutorials 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 can be found in the `YouTube channel of Exudyn `_ ! **NOTE**: **NumPy** switched to version 2.x which causes problems with packages that are not adapted to NumPy 2.x. The current version of Exudyn is already compatible with NumPy 2.x AND 1.x, however, some external packages (SciPy, robotics tools, etc.) may cause problems, therefore you could still use Numpy 1.26 (not available for Python >= 3.13). **NOTE**: We finally like to emphasize that this is an open source library; we receive no specific money and most developements are done during free (=night) time; some models are simplifications that work for our needs, but may not be appropriate in your case; some models are under development (usually stated in theDoc) or may have bugs, therefore do not fully rely on all elements of the library! Enjoy the Python library for multibody dynamics modeling, simulation, creating large scale systems, parameterized systems, component mode synthesis, optimization, ... Changes can be tracked in the :ref:`Issue tracker ` 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 `_ \ **READ Exudyn documentation** : `theDoc.pdf `_
