Mobile Multibody Dynamics (MOMDYN) is the first multibody dynamics app for Android. MOMDYN provides an easy to use graphical interface that is familiar to engineers and physicists who have studied classical mechanics, with a limited but powerful set of features similar to modern modeling and simulation software. The software forms a bridge between the"first-principles" approach to dynamics problem solving where one defines kinematic and dynamic equations by hand before developing custom code for each individual system, and the modern approach where the fundamental mathematical equations are obfuscated behind a purely graphical, computer aided design (CAD)-like interface.

MOMDYN 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, and you can even export custom Python code so you can simulate your system on a desktop. The app provides an entry point to learning multibody dynamics simulation, which will ease the learning curve for using modern scientific computing software.
