CAELinux is a live DVD Linux distribution dedicated to computer-aided engineering (CAD) and finite element analysis.
Based on the open-source CAD/CAM software such as FreeCAD, LibreCAD, PyCAM and CAE softwares like Salomé, Code_Aster, Code_Saturne, Calculix, 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.
