MBDyn is a multidisciplinary Multibody Dynamics scientific simulation software.

MBDyn is a general purpose multibody dynamics software coded in C++. It focuses on scientific validity of the results. It is and was used as a numerical simulation tool in major scientific research projects, of which some are listed here: http://tinyurl.com/jc5chmu

It features the integrated multidisciplinary simulation of multibody, multiphysics systems, including nonlinear mechanics of rigid and flexible bodies (geometrically exact & composite-ready beam and shell finite elements, component mode synthesis elements, lumped elements) subject to kinematic constraints, along with smart materials, electric networks, active control, hydraulic networks, and essential fixed-wing and rotorcraft aerodynamics.

MBDyn can be easily coupled to external solvers for co-simulation of multiphysics problems, e.g. Computational Fluid Dynamics (CFD), terradynamics, block-diagram solvers like Scicos, Scicoslab and Simulink, using a simple C, C++ or Python peer-side API.

Example MBDyn projects can be found: http://tinyurl.com/zutjwe7 Third party video examples made with MBDyn are also available: http://www.sky-engin.jp/en/ and

The principal developers of MBDyn work at the Department of Aerospace Engineering of the Polytechnic University of Milan (Politecnico di Milano). It is the largest technical university in Italy, with about 40,000 students. It offers undergraduate, graduate and higher education courses in engineering, architecture and design. Founded in 1863, it is also the oldest university in Milan.

The university was ranked the best for Engineering and among the top big universities in Italy in the CENSIS-Repubblica Italian University rankings for 2011-2012 and is ranked as the 28th best technical university in the world according to the QS World University Rankings.
