a parametric 3D CAD modeler
WARNING: FreeCAD has moved! FreeCAD code and release files are now hosted on github at https://github.com/FreeCAD/FreeCAD Only older files and code are available here. FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization. FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.

General Mission Analysis Tool
Do you want to go to Mars but don't know when to leave or how much to bring? Do you want to study Earth protection by planning a mission to a near-Earth asteroid? The General Mission Analysis Tool (GMAT) is an open-source space mission design tool to help you answer these and many other space flight challenges. GMAT is developed by a team of NASA, private industry, and public and private contributors. The GMAT development team is pleased to announce the release of GMAT version R2017a. For a complete list of new features, compatibility changes, and bug fixes, see the Release Notes. Below are just some of the new capabilities contained in this release. • New navigation data types • Preliminary Kalman filter • STK ephemeris propagation • Utility for managing data files (EOP etc.) • Collocation library • Preliminary API interface • Second level editing of navigation data
PICsim emulates a microcontroller PIC16F628/16F777/16F877A/18F452/18F4550/18F4620 and periferics such as USART and timers, the simulator architecture permit easy implementation of external elements in c language. PicsimLab is a realtime emulator of development boards with integrated MPLABX debugger.
GraphCalc is a very gui graphing calculator. It has been called a good replacement for a TI-85. It is a must for any high school math student.
ScadaBR is a SCADA (Supervisory Control and Data Acquisition) system with applications in Process Control and Automation, being developed and distributed using the open source model.
This small program can help you to calculate optimal cut of rectangular details. It can be used to design cutting out of wood, glass, steel and other material.
Program for minimizing boolean functions using Karnaugh maps method.
Molecular Dynamics Cell Construction
This is a collection of software modifications created to integrate NanoEngineer-1, PACKMOL and MSI2LMP for the purpose of easily creating molecular dynamics cells. NanoEngineer-1 is a molecular CAD software written by Nanorex and provides the user an easy way to create molecules, while the software modifications allow the user to type atoms using multiple force fields. PACKMOL can generate a random collection of molecules using the molecule templates from NanoEngineer-1 thus providing the initial MD cell. Modifications to PACKMOL allow the atom type data to be passed through to the MSI2LMP software. MSI2LMP creates a LAMMPS input file based on class I or class II force fields. MSI2LMP was modified to use numerically coded force field data generated by NanoEngineer-1. The MMP file format was extended and integrated into all three software applications. http://www.nanoengineer-1.net http://www.ime.unicamp.br/~martinez/packmol/ http://lammps.sandia.gov/
First-person 3D building and elevator simulator
Skyscraper is a fully featured first-person 3D virtual building simulator, written in C++ and using the OGRE graphics engine (previous versions used Crystal Space). It's flagship feature is an elaborate and realistic elevator simulator.
Data quality analysis, profiling, cleansing, duplicate detection +more
DataCleaner is a data quality analysis application and a solution platform for DQ solutions. It's core is a strong data profiling engine, which is extensible and thereby adds data cleansing, transformations, enrichment, deduplication, matching and merging. Website: http://datacleaner.github.io
The EQ mounts' internal electronics provides pointing accuracy to .144 arcsecs. EQMOD connects the EQ directly to a serial comms. This project has the source files for the Public releases of the EQMOD ASCOM driver, associated programs and an EQMOD compatible hardware design. Please note that later test releases for all EQMOD Project software may be available via the EQMOD Yahoo group.
Simple CAD program
ZCAD is simple CAD program with dxf2000 file format support. Source code available here http://svn.shamangrad.net/zcad/trunk/
GLUI is a GLUT-based C++ user interface library which provides controls such as buttons, checkboxes, radio buttons, and spinners to OpenGL applications. It is window-system independent, using GLUT or FreeGLUT.
GHDL - a VHDL simulator
GHDL is the leading open source VHDL simulator. *** Now on github.com/tgingold/ghdl *** We have binary distributions for Debian Linux, Mac OSX and Windows. On other systems, getting GHDL from here means downloading the current source package and building GHDL from source. Alternatively you can get the latest source version (warning : occasionally unstable!) by pulling a snapshot from the git repository.
ASCEND is a modelling environment and solver for large or small systems of non-linear equations, for use in engineering, thermodynamics, chemistry, physics, mathematics and biology. Solvers for both steady and dynamic (NLA & DAE) problems, are provid
FCSalyzer is a free program for analysing flow cytometry data
Impressum / Legal Notice Sven Mostböck Murlingengasse 25/5 1120 Wien Austria e-mail: firstname.lastname@example.org second contact option: use the open discussion on the FCSalyzer sourceforge page: http://sourceforge.net/p/fcsalyzer/discussion/ Information: FCSalyzer is a free program for analysing flow cytometry data. It is programmed in Java and should therefore work on many different operating systems. FCSalyzer offers an easy What-you-see-is-what-you get interface and provides the standard analysing tools - dot plots, histograms, complex gating strategies and associated statistics.
