Open CASCADE Technology, 3D modeling & numerical simulation.
Computer-aided engineering. MBDyn - MultiBody Dynamics. MBDyn is 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).
It has been developed at the Dipartimento di Scienze e Tecnologie Aerospaziali (formerly Dipartimento di Ingegneria Aerospaziale) of the University "Politecnico di Milano", Italy. MBDyn 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) subjected to kinematic constraints, along with smart materials, electric networks, active control, hydraulic networks, and essential fixed-wing and rotorcraft aerodynamics.

Friday, 14 October 2005 14:30 Joël Cugnoni Welcome to CAELinux.com, the website dedicated to the open source computer aided engineering Linux distribution CAElinux.
Thanks to Open Source, now you just need to insert the CAELinux LiveDVD in your computer to turn it into a free and open engineering development workstation with CAD, CAM, CAE / FEA / CFD, electronic design and 3D printing features: no licence and even no installation is required ! Based on the open-source CAD/CAM software such as Freecad, LibreCAD, PyCAM and Cura and CAE softwares like Salomé, Code_Aster, Code_Saturne, OpenFOAM and Elmer , you can design your CAD geometry, perform multiphysics simulations to optimize your design, generate G-code for prototyping with 3D printing & milling, and even develop your own PCBs & microcontroller based electronic circuits for automation.
