GeoPDEs is a suite of software tools for research on Isogeometric Analysis of PDEs. GeoPDEs is free software implemented in Octave and fully compatible with Matlab. GeoPDEs is no longer developed at SF, and has moved to GitHub. Please visit http://rafavzqz.github.io/geopdes/ The mailing list will remain active. Releases up to 2.0.4 can be found here. From version 2.1.0 onward, see https://github.com/rafavzqz/geopdes

Program was created for optimized packing of two dimensional rectangular elements at orthogonal table with main purpose of printing cutting sheets that can be used for cutting material at production in wood and panel furniture manufacturing. It is developed upon authors several years of experience at woodworking, and actual carpenters needs when such software is in question. In spite its look it is fully functional peace of software , with all necessary elements needed for generating cutting sheets. GUI is simple and it consists of fields for entering table and element dimensions on the right. Packing, optimization, cutting and cleaning table edges section bottom left and statistic section bottom right. Upper left are table description field and cut sheet drawing at the center. Right click at the cut sheet drawing and there are printing options. NOTICE : This program was not created for sellers of chipboard and other board materials. All the best, Author

The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a GObject-based library where a custom application can put common CAD entities such as paths, hatches and dimensions, to automatically create technical drawings. A demo application is provided in order to show the capabilities of the canvas. Although it is possible to interact with the library directly in C (that is what the adg-demo program is doing), the canvas is expected to be used from higher level languages, much in the same way as what done in the GNOME stack. Lua bindings based on LGI are already provided out of the box. The adg-lua project, downloadable from the "Files" section, provides Lua programs and demos that leverages these bindings.

This C++ demo allows users to interactively explore a quadtree's behavior. For this purpose the demo uses a quadtree data structure based on axis-aligned bounding boxes to speed up the search for triangles in a mesh. Depending on a search point all triangles of a quadtree's region are retrieved and relevant information about the search is shown. Quadtree creation can be parametrized by three parameters: - Maximum tree depth. - Maximum number of triangles per region. - Percentage of total number of triangles per region. The OpenGL graphics library is used to render the results, regions as well as the underlying triangle mesh. Navigation (e.g. zooming, moving) is available by keyboard and mouse. Example meshes are provided in wavefront *.obj format and can be opened from inside the program.

This plugin enable unsupported functionalities for Autodesk Inventor 2014 and above. Autodesk doesn't support Autorun macros for VBA projects anymore, but with this plugin it is still possible to use the commands "AutoOpen", "AutoEdit", "AutoSave", "AutoClose" and "AutoNew" subroutines stored within "Thisdocument" module.

FAST is an Analysis and Simulation Toolbox (FAST) for Fuel Cells (FC) FAST-FC is the doctorate work of David B. Harvey and was developed with support from the U.S. DOE, Ballard, and Queen's University. Derivative works of FAST-FC include FC-APOLLO which is a forked branch of this project intended to capture the code state at the exit of the funded DOE project. FAST-FC is the open and active community branch. FAST-FC is developed and maintained by the original creator and developer, David B. Harvey. Features of FAST-fc include transport of gases and liquids, multi-step reaction kinetics, transient and steady state operation for performance and durability, and scalable dimensionality from 1D - 3D domains. Future development work is on-going in FAST-fc and our strategic development schedule includes membrane degradation, improved liquid water transport models through the application of pore networks, and extension to stack-level simulation.

IdCREATE stands for "Idea Creation, Representation & Execution Automated Tools and Engine". This is intended to be a graphical tool for 1) representing your thoughts and ideas in a mindmap-like charts and 2) implementing them as code, article text, etc

Typically, to program a GUI is time consuming and requires experience with graphic libraries. OpenNum lets you create a graphical interface adapted to your solvers by simply editing an XML configuration file. More specifically, OpenNum lets you · to collect a hierarchical dataset, · to call any executable file and · to visualize scalar and vector fields, plot graphs or show simple plain text files. It also has other useful utilities specifically designed for numerical simulation packages: · it allows managing a centralized materials dataset; · it can read several finite element mesh formats and several field formats.

The PARSEC CEE is the primary achievement of several years of effort at NASA's Marshall Space Flight Center. The CEE was developed to allow engineers in the Advanced Concepts Department to rapidly prototype launch vehicle and spacecraft concepts.

A java based editor for creating 3D indoor environments based on 2D input.

Version Control for engineers (SVN edition) is a freeware Windows collaboration tool for engineers, scientist and designers. Version Control for engineers give you the file revision control for your hardware, engineering and scientific projects. Version Control for engineers is graphical user interface for SVN (Apache Subversion, http://subversion.apache.org/) version control system, special optimized for image, CAD/CAM files and technical visuals. Program supports the file, http and https connection to SVN repositories. Also see the Portable Edition https://sourceforge.net/projects/portable.postpdm.p/

libdwg-testsuite is a test suite for libdwg. libdwg is "An open C library to directly read DWG files, a popular drawing format used in the CAD world." https://sourceforge.net/projects/libdwg/

Clothes - sewing CAD for creation of models of clothes. Based on the new concept of the automated designing of clothes with use of parametrical model. Creates a base design of model of clothes and allows to change it depending on necessity of updating.
