Multibody Dynamics and Multidisciplinary Analysis and Related Software

Free/Libre, Open Source Software, and other easily accessible stuff

Multibody

• 3d_mec: a program for numerical, symbolical and graphical treatment of vectorial expressions and equations in mechanics.
• Computational technologies for the visualization of symbolically modeled problems in engineering dynamics
  A set of package demos for the symbolic solution of open-loop rigid body systems (within Mathematica, not all that free software, though) and the numerical solution of rigid-body and beam-like open-loop systems in a Lagrangian approach. The two use a GUI based on Open CASCADE, a LGPL-like (but carefully read the license) C++ library for building GUIs. The license of the multibody software and of the GUI is unclear, but all products can be downloaded after sending an email to the developer.
• DynaFlex
• DynaMechs
• EasyDyn: a C++ library for the simulation of problems represented by second-order (or first-order) differential equations and, more particularly, multibody systems.
• KinSynth: a website for multibody-related educational software discussion and exchange, hosted by Università La Sapienza, Roma.
• MBDyn
• MBS3D: an easy-to-use open-source general-purpose program for the dynamic simulation of multibody systems. It is entirely programmed as plain-text in MATLAB and uses a very efficient and tested mathematical semi-recursive formulation. It covers open-chain and closed-loop systems.
• MechXML: a draft for a new language to define Multibody Systems. It is based on XML (eXtensible Markup Language), the standard meta-language to data interchange. In the current version, only rigid bodies are being considered.
• Open Dynamics Engine
• Robotran: ROBOTRAN is a computer program which generates kinematic and dynamical models of multibody systems in a symbolic manner.

Aerospace

• FreeCASE: DIAPM's Free(dom) Computational AeroServoElasticity site hosts links to the free software they develop.
• NeoCASS (Next generation Conceptual Aero Structural Sizing) is a free suite of Matlab modules that combines state of the art computational, analytical and semi-empirical methods to tackle all the aspects of the aero-structural analysis of a design layout at conceptual design stage.
• OpenFOAM
