Impact is an explicit Finite Element Program Suite which simulates dynamic impact events. It has a range of elements, contact handling and different material laws. Models can be created, solved and analyzed with the included pre- and postprocessor. Impact is based on an Explicit Time stepping algorithm. These kind of codes are used to simulate dynamic phenomena such as car crashes and similar, usually involving large deformations.

Fachwerk3D calculates three-dimensional strut-and-tie models used by structural engineers for analysing and designing reinforced concrete structures. The program only uses the equilibrium conditions, thus it is not assuming elastic behaviour.

CNC code generator is a software to generate CNC codes (G & M codes) for maching operations like milling, drilling. At present CNC code generator is limited for end milling. we working on other machining operations like turning, drilling etc.

APP for Android 3.1 or greater to implement a CNC Controller that send orders using USB port to Arduino Mega 2560 R3 board to control 3 stepper motor to have a real CNC mill /// APP para Android 3.1 o superior para implementar un Controlador de CNC que envia ordenes usando el puerto USB a la placa Arduino Mega 2560 R3 para controlar 3 motores paso a paso para tener una fresadora de CNC real.

Wuweido is a professional 3D CAD on your phone or tablet. More than just a viewer, dozens of modeling tools are provided to create and modify 3D models in the most natural way. Wuweido allows you to import and export models in standard CAD format. Unlike Onshape™ on Cloud, Wuweido is running locally on your device and it's more like Rhino™ 3D on mobile. Wuweido is powered by OPEN CASCADE. OPEN CASCADE is an incredible powerful geometry kernel innovating quickly. Wuweido is inspired by CAD Assistant. Modeling features: 1. Draft creation tools: Line, Poly Line, Arc, Spline, Circle, Ellipse, Rectangle, Regular Polygon. 2. Primitive Solid creation tools: Box, Cone, Truncated Cone, Cylinder, Sphere, Torus, Wedge, Truncated Wedge, Pyramid, Truncated Pyramid. 3. Sweep modeling tools: Extrude, Revolve, Loft, Pipe, Path 4. Boolean operation tools: Intersect, Subtract, Union, Xor, Fuse 5. Transform tools: Move, Rotate, Mirror, Scale

COPanno is now at http://download.tuxfamily.org/copanno/ COPanno is a small utility to find the best solution for cutting rectangular panels in a defined-size sheet. * v1.2 Introduce multi-threading (calculation is up to 8 times faster) and internationalization support. English and French translations are done. * v1.3 Add per panel orientation keeping Copanno est un utilitaire de calepinage donnant la meilleure manière de découper des panneaux rectangulaire dans une feuille de dimension définie. * v1.2 Le calcul parallèle permet d'accélérer le traitement sur les ordinateurs multi-cœurs. La traduction en Français et en Anglais est réalisée. * v1.3 La conservation de l'orientation des panneaux (le fil) peut être définie pour chaque élément.

GeomSS is a geometry modeling and scripting system in Java. Write scripts that create and analyze complex geometry including NURBS curves and surfaces. This is especially useful for tasks that must be repeated with small or parametric variations.

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.

Software application, firmware and U.I. for 4-motors 3-axis milling machine, open hardware, software and mechanics. See also project in details for schematics and images on http://www.contesti.eu/opensource/xyz-dc-motor-controller

Basics of a CAD System. Lets users build 3D model of different geometry. Select properties and Analyze using FEM to get stress and displacements under loading.

Line-drawing and polygon-filling rasterization algorithms in Java. Simple 2D package and more complex 3D package with Z-buffering. Texture mapping not supported at the moment. Color interpolation for lines, Gouraud shading for polygons fully supported. Floating point vertex coordinates, not integer. Pixel-level aliasing, not endpoint aliasing. Doesn't use Bresenham line style! Works with all Java versions. No external dependencies. Suitable for study in academic institutions, especially as related to line-drawing accuracy. Particular attention to detail concerning chopping of accumulation errors, using a cast from 64 bit to 32 bit strategy, in the interval [1.0,2.0). Individual pixel errors with overlapping polygons or line segments are about one in a billion, but I can't reproduce any errors at the moment by using random number generation with tens of millions of cases. Emphasis not only on correctness, but also on performance for real-world use or hardware implementation.

Java application for virtual tool shop simulation. Application allows simulation of exchange jobs between some tool shops. Jobs are grouped in projects and are organized in Petri nets (sequences of activities and stores).
