SALOME is an open-source software that provides a generic Pre- and Post-Processing platform for numerical simulation. It can be used as a standalone application for generation of the CAD model, its preparation for the numerical calculations and post-processing of the calculation results or as a platform for integration of the external third-party numerical codes to produce a new application for the full life-cycle management of CAD models.

FreeCAD is a multi-use parametric 3D modeler or CAD system, which development is entirely based on the principles of the Open Source Code (LGPL License). FreeCAD directly targets development in mechanical engineering and object design. It is also suitable for a wider range of engineering applications such as architecture, endpoint analysis, 3D printing and others.
