FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. It is designed to fit a wide range of uses including product design, mechanical engineering, architecture and 3D printing.FreeCAD allows you to sketch geometry constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production-ready drawings. it is a multiplatfom (Windows, Mac and Linux), highly customizable using the Python language. It reads and writes to many open file formats such as STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE and many others, making it possible to seamlessly integrate it into your workflow.FreeCAD includes a modern Finite Element Analysis (FEA) tools, experimental CFD, BIM, Geodata workbenches, a Path (CNC) workbench, a robot simulation module that allows you to study robot movements and many more, and a rich collection of plugins and macros installable directly from within the application.

      GNU Octave is a high-level interpreted language, primarily intended for
      numerical computations. It provides capabilities for the numerical
      solution of linear and nonlinear problems, and for performing other
      numerical experiments. It also provides extensive graphics capabilities
      for data visualization and manipulation. Octave is normally used through
      its interactive command line interface, but it can also be used to write
      non-interactive programs. The Octave language is quite similar to
      Matlab so that most programs are easily portable.
    
      
      Octave has extensive tools for solving common numerical linear algebra
      problems, finding the roots of nonlinear equations, integrating ordinary
      functions, manipulating polynomials, and integrating ordinary
      differential and differential-algebraic equations. It is easily
      extensible and customizable via user-defined functions written in
      Octave's own language, or using dynamically loaded modules written in
      C++, C, Fortran, or other languages.

	    LyX combines the power and flexibility of TeX/LaTeX with the
	    ease of use of a graphical interface. This results in
	    world-class support for creation of mathematical content (via a
	    fully integrated equation editor) and structured documents like
	    academic articles, theses, and books. In addition, staples of
	    scientific authoring such as reference list and index creation
	    come standard. But you can also use LyX to create a letter or a
	    novel or a theatre play or film script. A broad array of ready,
	    well-designed document layouts are built in.
	
      
	    LyX is for people who want their writing to look great,
	    right out of the box. No more endless tinkering with formatting
	    details, “finger painting” font attributes or futzing around
	    with page boundaries. You just write. On screen, LyX looks like
	    any word processor; its printed output — or richly
	    cross-referenced PDF, just as readily produced — looks like
    	    nothing else.
