MBDyn is described as 'The first and possibly the only free* general purpose Multibody Dynamics analysis software, released under GNU's GPL 2.1 (get a cached copy here)' and is an app. There are seven alternatives to MBDyn for Windows and Linux. The best MBDyn alternative is QuickField, which is free. Other great apps like MBDyn are RoboAnalizer, CarSim, RecurDyn and mbsim-env.

RoboAnalyzer is a 3D model based software that can be used to teach and learn the Robotics concepts. It is an evolving product developed in Mechatronics Lab, Department of Mechanical Engineering at IIT Delhi, New Delhi, India, under the guidance of Prof. S.K.
Computer simulation of vehicle dynamics for ride, handling, braking, and acceleration of cars, trucks, motorcycles, and motorsports with Windows OS and real-time systems.
RecurDyn is Computer Aided Engineering (CAE) software that is focused on Multibody Dynamics (MBD), while offering multiphysics solutions. The technology behind RecurDyn has superior calculation efficiency because it is based on recursive formulation.
MBSim is a multi-body simulation software. Its purpose is the simulation of the dynamics of mechanical systems.
SIMPACK is a general purpose Multi-Body Simulation (MBS) software which is used for the dynamic analysis of any mechanical or mechatronic system.
