Mobile Multibody Dynamics (MOMDYN) is a full version Android app that provides an easy-to-use graphical interface for engineers and physicists who have studied classical mechanics. The app offers a limited but powerful set of features similar to modern modeling and simulation software. It is an excellent educational resource for students enrolled in dynamics, vibration, or structural analysis coursework as part of a mechanical or aerospace engineering program. The modeling process and equations are all visible to the user, making it an entry point to learning multibody dynamics simulation. MOMDYN is an accessible alternative for engineering students or developing professionals who want to learn the basic principles behind how advanced software works so they can feel confident in applying those tools in their future careers.

MOMDYN provides the ability to export custom Python code so you can simulate your system on a desktop. With the Export menu, you can choose to automatically generate Python source code that will replicate the same equations and parameters that you set up on your device, and can be executed in a Python environment using common and freely available packages. MOMDYN lets you build on your ideas in the moment, and watch them take motion in the palm of your hand. It is an excellent tool for anyone who wants to run their model once or twice but is not looking to run 100,000 cases in a Monte Carlo study.
