Symbolic Multi-Body Dynamics in Python | A python package for symbolic creation and analysis of constrained multi-body systems

Please visit uraeus.mbd for more information about audience , fields of applications and background.

• Creation of symbolic template-based and standalone multi-body systems using minimal API via python scripting.
• Convenient and easy creation of complex multi-body assemblies.
• Convenient visualization of the system topology as a network graph.
• Viewing the system's symbolic equations in a natural mathematical format using Latex printing.
• Optimization of the system symbolic equations by performing common sub-expressions elimination.
• Creation of symbolic configuration files to facilitate the process of numerical simulation data entry.

The documentation is hosted at readthedocs and can be found here.

The package needs a valid python 3.6+ environment. If new to scientific computing in python, Anaconda is a recommended free python distribution from Continuum Analytics that includes SymPy, SciPy, NumPy, Matplotlib, and many more useful packages for scientific computing, which provides a nice coherent platform with most of the tools needed.

As the package is still under continuous development, cloning this repository is a more versatile way to test and play with it, until a more stable first release is released. This can be done via the following git command using the terminal (Linux and Mac) or powershell (Windows).

git clone https://github.com/khaledghobashy/uraeus_smbd.git

This will download the repository locally on your machine. To install the package locally and use it as other python packages, using the same terminal/powershell run the following command:

pip install -e uraeus_smbd

The Implementation Details will be provided in a separate documentation and linked here

The Theoretical Basis will be provided in a separate documentation and linked here

As the tool is developed and maintained by one developer for now, if you have any inquiries, do not hesitate to contact me at [email protected] or [email protected]
