G-Code Ripper reads g-code, scales, and rotates and/or splits the tool paths before outputting the modified tool path data to a new g-code file. It evaluates g-code expressions and parameters and interprets YZ and ZX arcs. YZ and ZX arcs are internally converted to linear motions for compatibility with splitting and rotation.
F-Engrave generates g-code tool paths for CNC machines using CXF fonts, true type fonts (TTF), or a 2D DXF file. It can generate tool paths for engraving or v-carving text or a DXF design. The output of F-Engrave can be imported into EMC2, MACH3, or other machine controllers. F-Engrave output can be reopened by F-Engrave for later editing. F-Engrave designs can also be exported as SVG files.
astroPluto is modular Godunov-type code intended mainly for astrophysical applications and high Mach number flows in multiple spatial dimensions. The code embeds different hydrodynamic modules and multiple algorithms to solve the equations describing Newtonian, relativistic, MHD, or relativistic MHD fluids in Cartesian or curvilinear coordinates.
MakeHuman is software for the modelling of three-dimensional humanoid characters. Features that make this software unique include a highly intuitive GUI and a high quality mesh, optimized to work in subdivision surface mode (for example, Zbrush). Using MakeHuman, a photo-realistic character can be modelled in less than 2 minutes.
ElectricFormula is a program that can help with electronic based projects or problems. It can calculate electric power, resistance, current, or voltage. If given two of these variables as input, it can determine the other two. For example, if you want to calculate the resistance, you will have to supply the value for the electric power and current or you can supply the value of the power and voltage.
Z88 is a fast, powerful, and compact finite elements analysis program. Z88 features 20 finite element types; it covers plane stress, plate bending, axial symmetric structures, and spacial structures up to 20-node Serendipity hexahedrons. It comes with a user-friendly interface (the Z88 Commander), and has a powerful mesh generator. It features a DXF coverter and two plot programs. The FEA solver is included, featuring an in-situ Cholesky solver along with the Jennings storage method. COSMOS and NASTRAN files from Pro/ENGINEER can be imported. Z88 is a project of the University of Bayreuth, Germany.
Meep is a free finite-difference time-domain (FDTD) simulation software package to model electromagnetic systems. It supports distributed-memory parallel simulations, nonlinear, anisotropic, and dispersive media, PML absorbing boundaries, and 1D/2D/3D and cylindrical problems. It is completely scriptable from either C++ or a Scheme (GNU Guile) interface.
FreeCAD is a CAx RAD based on OpenCASCADE, Qt4, and Python. It features some key concepts like Macro recording, Workbenches, and the ability to run as a server. It's also platform-independent. It is is fully scriptable and designed to be easily extensible; only the core functionality is embedded into the core libraries, but all further functionality like support of triangle meshes, CAM, FEM, etc. is implemented in extension modules. Normally, such a module is divided into an 'App' part containing the data structures and algorithms and a 'GUI' containing the graphical representation of data structures, dialogs, workbenches, etc.
glfer is a GTK+ application that shows the input signal frequency spectrum in a waterfall display and can also control a transmitter to emit slow-CW (QRSS) signals. The signal to be analyzed can be acquired in real-time from the sound card or can be read from a WAV file. The signal spectrum can be computed using four different spectral estimators. The spectrogram display can be saved as an image; you can choose to save the entire window, or select a rectangular region to save with the mouse.
